EPSS score
1.34%
Cloud Foundry Cloud Controller API Release, versions prior to 1.79.0, contains improper authentication when validating user permissions. A remote authenticated malicious user with the ability to create UAA clients and knowledge of the email of a victim in the foundation may escalate their privileges to that of the victim by creating a client with a name equal to the guid of their victim.

CF CLI version prior to v6.45.0 (bosh release version 1.16.0) writes the client id and secret to its config file when the user authenticates with --client-credentials flag. A local authenticated malicious user with access to the CF CLI config file can act as that client, who is the owner of the leaked credentials.
6.5CVE-2019-3794cloud foundryuaa release (oss)+1
EPSS score
1.07%
Cloud Foundry UAA, versions prior to v73.4.0, does not set an X-FRAME-OPTIONS header on various endpoints. A remote user can perform clickjacking attacks on UAA's frontend sites.
7.7CVE-2019-3786cloud foundrybosh backup and restore+1
EPSS score
0.58%
Cloud Foundry BOSH Backup and Restore CLI, all versions prior to 1.5.0, does not check the authenticity of backup scripts in BOSH. A remote authenticated malicious user can modify the metadata file of a Bosh Backup and Restore job to request extra backup files from different jobs upon restore. The exploited hooks in this metadata script were only maintained in the cfcr-etcd-release, so clusters deployed with the BBR job for etcd in this release are vulnerable.
8.8CVE-2019-3789cloud foundrycf routing+1
EPSS score
0.76%
Cloud Foundry Routing Release, all versions prior to 0.188.0, contains a vulnerability that can hijack the traffic to route services hosted outside the platform. A user with space developer permissions can create a private domain that shadows the external domain of the route service, and map that route to an app. When the gorouter receives traffic destined for the external route service, this traffic will instead be directed to the internal app using the shadow route.
9.8CVE-2019-3801cloud foundrycf-deployment+6
EPSS score
0.59%
Cloud Foundry cf-deployment, versions prior to 7.9.0, contain java components that are using an insecure protocol to fetch dependencies when building. A remote unauthenticated malicious attacker could hijack the DNS entry for the dependency, and inject malicious code into the component.
8.8CVE-2019-3781cloud foundrycf cli+3
EPSS score
1.33%
Cloud Foundry CLI, versions prior to v6.43.0, improperly exposes passwords when verbose/trace/debugging is turned on. A local unauthenticated or remote authenticated malicious user with access to logs may gain part or all of a users password.
8.2CVE-2019-3784cloud foundrystratos+1
EPSS score
1.06%
Cloud Foundry Stratos, versions prior to 2.3.0, contains an insecure session that can be spoofed. When deployed on cloud foundry with multiple instances using the default embedded SQLite database, a remote authenticated malicious user can switch sessions to another user with the same session id.
6.5CVE-2026-59357cloud foundrycf-deployment+1
EPSS score
0.18%
Insufficient verification of data authenticity (CWE-345) in the external OIDC login callback in Cloud Foundry UAA v4.5.0 to v79.6.0 (inclusive) allows an authenticated UAA user to bypass the OAuth authorization-code exchange and establish an authenticated external-OIDC browser session, via submitting a UAA access token or a cross-client ID token as the callback’s id_token parameter. The issue only manifests when a UAA zone is configured with an OIDC identity provider whose issuer exactly matches that zone’s own /oauth/token endpoint (a “self-UAA” OIDC configuration). In this configuration, the callback takes a supplied id_token directly instead of requiring the authorization code exchange, and does not verify that the token was actually issued as an ID token for the specific self-OIDC relying-party client. An attacker holding any valid UAA JWT for themselves — including a plain access token with only uaa.user scope, or a valid ID token issued to an unrelated client such as cf — can present it as the callback’s id_token and be authenticated into a mapped local (“shadow”) account. Because the resulting session is not verified against the originating token’s true audience or user_id, its effective privilege depends entirely on the shadow account’s group memberships, which can include administrative scopes such as clients.write. Exploitation requires a valid UAA user JWT, a valid browser login state for the target zone, and the presence of a self-referential OIDC provider configuration — this is not a pre-authentication vulnerability, and does not by itself grant privileges beyond those already held by the mapped shadow account.
8.7CVE-2026-59335cloud foundrycf-deployment+1
EPSS score
0.53%
Improper handling of case sensitivity (CWE-178) in the identity zone authorization check in the Identity Zone Endpoint in Cloud Foundry UAA allows a remote authenticated attacker holding only the zones.write authority to bypass the intended restriction that this authority does not grant access to the privileged uaa (system) identity zone, by referring to the zone identifier in a non-lowercase form (e.g. UAA) in the request path and body. The authorization layer performs a case-sensitive comparison against the system zone identifier, while the underlying MySQL persistence layer resolves identifiers case-insensitively under its default collation, so the request is authorized incorrectly and is then resolved against the real system zone record. This allows the attacker to overwrite the system zone's JWT signing key with attacker-controlled key material, forge JWTs claiming the admin client and administrator scopes, and fully compromise UAA and any Cloud Foundry deployment that trusts it. This issue only affects UAA deployments backed by MySQL using its default collation; PostgreSQL and HSQLDB backends are not affected.
7.6CVE-2026-59358cloud foundrycf-deployment+1
EPSS score
0.35%
Improper authentication (CWE-287) in the OAuth token endpoint in Cloud Foundry UAA allows a remote, authenticated attacker holding a valid user access token to obtain a fully-privileged client_credentials token for the OAuth client that issued it, by presenting the user token as an OAuth 2.0 Bearer credential on a client_credentials grant request in place of the client’s configured secret. UAA’s client_credentials handling does not verify that the Bearer credential supplied for client authentication is actually a client credential (a client secret or a valid configured client authentication method); it accepts any valid access token whose client_id matches the request. A token obtained by a normal end user through a public authorization_code + PKCE flow — scoped only to uaa.user, carrying a user_id, and recording client_auth_method=none — satisfies this check. That user token cannot itself administer OAuth clients (POST /oauth/clients correctly returns 403), but when replayed as Bearer authentication on a client_credentials request for the same client, UAA issues a new client-only token carrying the client’s full authorities, such as clients.write. An attacker can use that token to create arbitrary new OAuth clients, including clients with attacker-chosen authorities, without ever possessing the client’s actual secret. Exploitation requires a valid user access token (the attacker’s own) for a client that is configured to support both a public, user-facing authorization flow and the client_credentials grant type on the same client_id — a non-default combination. Practical impact scales with the authorities assigned to that client.
9CVE-2026-41005cloud foundrycf deployment+1
EPSS score
0.16%
Cloud Foundry UAA incorrectly treated XML encryption to the Service Provider (confidentiality) as a substitute for XML signatures from the Identity Provider (authenticity) in two SAML flows: the OAuth 2.0 SAML2 bearer grant (token endpoint) and browser SSO (ACS) when wantAssertionSigned is set to false. Assertions or responses that were unsigned but contained encrypted content could still be accepted. Encryption uses the SP's public key from published metadata, therefore, any party, not only a trusted IdP, can produce ciphertext UAA can decrypt; successful decryption therefore does not prove the IdP issued the message. Affected versions: Cloud Foundry UAA (uaa_release) 2.0.0 through 78.13.0. Cloud Foundry CF Deployment all versions through 56.1.0.
7.7CVE-2026-41012cloud foundrybosh-vsphere-cpi-release
EPSS score
0.10%
Traffic interception vulnerability in BOSH Director vCenter CPI allows attackers positioned between BOSH Director and vCenter to impersonate vCenter REST API and capture administrator credentials via HTTP Basic auth, leading to complete virtualization infrastructure takeover. An attacker who can intercept traffic between the BOSH Director and vCenter can establish a malicious server impersonating the vCenter REST API. When the BOSH Director makes CPI calls to perform routine cloud infrastructure operations, the attacker captures the vCenter administrator username and password transmitted via HTTP Basic authentication. The vulnerability stems from insufficient authentication security in the communication protocol between BOSH Director and vCenter. While HTTPS may be used, the lack of proper certificate validation and pinning allows attackers to successfully impersonate vCenter endpoints. Because vCenter credentials typically grant full administrative control over the entire virtualization estate, successful credential capture yields complete takeover of every VM, datastore, and network the CPI manages. This exposure exists on every CPI call (including routine deployment operations, not just when tags are configured) and cannot be mitigated by supplying a CA certificate alone. The attack impacts all infrastructure managed by the compromised vCenter instance, potentially affecting hundreds or thousands of VMs across multiple deployments and environments.
5.8CVE-2026-41009cloud foundry foundationbosh director+1
EPSS score
0.13%
When the director sends a long-running request (e.g. compile_package), the agent's reply JSON is consumed by AgentClient. inject_compile_log (line 332-339) reads response['value']['result']['compile_log_id'] and format_exception (line 318-325) reads exception['blobstore_id']; both pass the agent-supplied string unmodified to download_and_delete_blob(blob_id) (line 344-349), which calls @resource_manager.get_resource(blob_id) and, in an ensure block, @resource_manager.delete_resource(blob_id). Api::ResourceManager forwards the id straight to blobstore.get(id) / blobstore.delete(id). When the director is configured with the local blobstore provider, Blobstore::LocalClient#object_file_path(oid) is File.join(@blobstore_path, oid) (local_client.rb:54-56) with no normalisation, so oid = "../../jobs/director/config/director.yml" resolves outside the blobstore root. Affected versions: BOSH Director: All versions prior to v282.1.12
6.8CVE-2026-41704cloud foundry foundationbosh director+1
EPSS score
0.11%
AgentClient#handle_method (lines 264-303) processes every NATS reply. It calls inject_compile_log (line 273) on every response, which reads response['value']['result']['compile_log_id'] (line 332-338) and passes it to download_and_delete_blob. Separately, any response containing 'exception' goes through format_exception (lines 308-325), which reads exception['blobstore_id'] and also calls download_and_delete_blob. That helper (lines 344-349) calls ResourceManager#get_resource(blob_id) and, in an ensure block, ResourceManager#delete_resource(blob_id). ResourceManager (resource_manager.rb:62-70) calls blobstore.delete(id) on the single shared Director blobstore with no UUID-format check, no ownership check, and no namespace prefix. Affected versions: BOSH Director: All versions prior to v282.1.12
8.6CVE-2026-22734cloud foundryuua
EPSS score
0.36%
Cloud Foundry UUA is vulnerable to a bypass that allows an attacker to obtain a token for any user and gain access to UAA-protected systems. This vulnerability exists when SAML 2.0 bearer assertions are enabled for a client, as the UAA accepts SAML 2.0 bearer assertions that are neither signed nor encrypted. This issue affects UUA from v77.30.0 to v78.7.0 (inclusive) and it affects CF Deployment from v48.7.0 to v54.14.0 (inclusive).
