EPSS score
1.39%
mcrypt_get_block_size did not enforce that the provided "module" parameter was a string, leading to type confusion if other types of data were passed in. This issue affects HHVM versions prior to 3.9.5, all versions between 3.10.0 and 3.12.3 (inclusive), and all versions between 3.13.0 and 3.14.1 (inclusive).

hhvm before 3.12.11 has a use-after-free in the serialize_memoize_param() and ResourceBundle::__construct() functions.
5.3CVE-2016-1000109ubuntuhhvm+1
EPSS score
5.08%
HHVM does not attempt to address RFC 3875 section 4.1.18 namespace conflicts and therefore does not protect CGI applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect a CGI application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. This issue affects HHVM versions prior to 3.9.6, all versions between 3.10.0 and 3.12.4 (inclusive), and all versions between 3.13.0 and 3.14.2 (inclusive).

5.3CVE-2025-55183facebookreact+7
EPSS score
64.23%
An information leak vulnerability exists in specific configurations of React Server Components versions 19.0.0, 19.0.1 19.1.0, 19.1.1, 19.1.2, 19.2.0 and 19.2.1, including the following packages: react-server-dom-parcel, react-server-dom-turbopack, and react-server-dom-webpack. A specifically crafted HTTP request sent to a vulnerable Server Function may unsafely return the source code of any Server Function. Exploitation requires the existence of a Server Function which explicitly or implicitly exposes a stringified argument.
5.3CVE-2025-55181facebookproxygen
EPSS score
0.29%
Sending an HTTP request/response body with greater than 2^31 bytes triggers an infinite loop in proxygen::coro::HTTPQuicCoroSession which blocks the backing event loop and unconditionally appends data to a std::vector per-loop iteration. This issue leads to unbounded memory growth and eventually causes the process to run out of memory.
5.4CVE-2025-55177facebookwhatsapp business for ios+4KEV
EPSS score
4.73%
Incomplete authorization of linked device synchronization messages in WhatsApp for iOS prior to v2.25.21.73, WhatsApp Business for iOS v2.25.21.78, and WhatsApp for Mac v2.25.21.78 could have allowed an unrelated user to trigger processing of content from an arbitrary URL on a target’s device. We assess that this vulnerability, in combination with an OS-level vulnerability on Apple platforms (CVE-2025-43300), may have been exploited in a sophisticated attack against specific targeted users.
7.5CVE-2025-55184facebookreact+7
EPSS score
66.88%
A pre-authentication denial of service vulnerability exists in React Server Components versions 19.0.0, 19.0.1 19.1.0, 19.1.1, 19.1.2, 19.2.0 and 19.2.1, including the following packages: react-server-dom-parcel, react-server-dom-turbopack, and react-server-dom-webpack. The vulnerable code unsafely deserializes payloads from HTTP requests to Server Function endpoints, which can cause an infinite loop that hangs the server process and may prevent future HTTP requests from being served.
10CVE-2025-55182facebookreact+7KEVRansomware
EPSS score
99.80%
A pre-authentication remote code execution vulnerability exists in React Server Components versions 19.0.0, 19.1.0, 19.1.1, and 19.2.0 including the following packages: react-server-dom-parcel, react-server-dom-turbopack, and react-server-dom-webpack. The vulnerable code unsafely deserializes payloads from HTTP requests to Server Function endpoints.
5.4CVE-2025-55179facebookwhatsapp business for ios+4
EPSS score
0.18%
Incomplete validation of rich response messages in WhatsApp for iOS prior to v2.25.23.73, WhatsApp Business for iOS v2.25.23.82, and WhatsApp for Mac v2.25.23.83 could have allowed a user to trigger processing of media content from an arbitrary URL on another user’s device. We have not seen evidence of exploitation in the wild.
6.8CVE-2025-27591Crates.Iobelow+3
EPSS score
0.37%
A privilege escalation vulnerability existed in the Below service prior to v0.9.0 due to the creation of a world-writable directory at /var/log/below. This could have allowed local unprivileged users to escalate to root privileges through symlink attacks that manipulate files such as /etc/shadow.
7.5CVE-2025-67779facebookreact+7
EPSS score
19.99%
It was found that the fix addressing CVE-2025-55184 in React Server Components was incomplete and does not prevent a denial of service attack in a specific case. React Server Components versions 19.0.2, 19.1.3 and 19.2.2 are affected, allowing unsafe deserialization of payloads from HTTP requests to Server Function endpoints. This can cause an infinite loop that hangs the server process and may prevent future HTTP requests from being served.
5.3CVE-2025-64296facebookfacebook_for_woocommerce+1
EPSS score
0.22%
Missing Authorization vulnerability in Facebook Facebook for WooCommerce facebook-for-woocommerce allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Facebook for WooCommerce: from n/a through <= 3.5.7.
8.1CVE-2025-30403facebookmvfst
EPSS score
0.33%
A heap-buffer-overflow vulnerability is possible in mvfst via a specially crafted message during a QUIC session. This issue affects mvfst versions prior to v2025.07.07.00.
6.7CVE-2025-30401facebookwhatsapp desktop for windows+1
EPSS score
20.99%
A spoofing issue in WhatsApp for Windows prior to version 2.2450.6 displayed attachments according to their MIME type but selected the file opening handler based on the attachment’s filename extension. A maliciously crafted mismatch could have caused the recipient to inadvertently execute arbitrary code rather than view the attachment when manually opening the attachment inside WhatsApp. We have not seen evidence of exploitation in the wild.
