CVE-2018-1322apache software foundationapache syncope+28y ago20-03-2018 17:00

An administrator with user search entitlements in Apache Syncope 1.2.x before 1.2.11, 2.0.x before 2.0.8, and unsupported releases 1.0.x and 1.1.x which may be also affected, can recover sensitive security values using the fiql and orderby parameters.CVE-2018-1321apache software foundationapache syncope+28y ago20-03-2018 17:00

An administrator with report and template entitlements in Apache Syncope 1.2.x before 1.2.11, 2.0.x before 2.0.8, and unsupported releases 1.0.x and 1.1.x which may be also affected, can use XSL Transformations (XSLT) to perform malicious operations, including but not limited to file read, file write, and code execution.CVE-2018-17184apache software foundationapache syncope+27y ago06-11-2018 19:00

A malicious user with enough administration entitlements can inject html-like elements containing JavaScript statements into Connector names, Report names, AnyTypeClass keys and Policy descriptions. When another user with enough administration entitlements edits one of the Entities above via Admin Console, the injected JavaScript code is executed.CVE-2018-17186apache software foundationapache syncope+27y ago06-11-2018 21:00

An administrator with workflow definition entitlements can use DTD to perform malicious operations, including but not limited to file read, file write, and code execution.CVE-2025-65998apache software foundationapache syncope+210mo ago24-11-2025 13:47

Apache Syncope can be configured to store the user password values in the internal database with AES encryption, though this is not the default option. When AES is configured, the default key value, hard-coded in the source code, is always used. This allows a malicious attacker, once obtained access to the internal database content, to reconstruct the original cleartext password values. This is not affecting encrypted plain attributes, whose values are also stored using AES encryption. Users are recommended to upgrade to version 3.0.15 / 4.0.3, which fix this issue.CVE-2025-57738apache software foundationapache syncope+212mo ago20-10-2025 14:43

Apache Syncope offers the ability to extend / customize the base behavior on every deployment by allowing to provide custom implementations of a few Java interfaces; such implementations can be provided either as Java or Groovy classes, with the latter being particularly attractive as the machinery is set for runtime reload. Such a feature has been available for a while, but recently it was discovered that a malicious administrator can inject Groovy code that can be executed remotely by a running Apache Syncope Core instance. Users are recommended to upgrade to version 3.0.14 / 4.0.2, which fix this issue by forcing the Groovy code to run in a sandbox.CVE-2020-1959apachesyncope+16y ago04-05-2020 12:25

A Server-Side Template Injection was identified in Apache Syncope prior to 2.1.6 enabling attackers to inject arbitrary Java EL expressions, leading to an unauthenticated Remote Code Execution (RCE) vulnerability. Apache Syncope uses Java Bean Validation (JSR 380) custom constraint validators. When building custom constraint violation error messages, they support different types of interpolation, including Java EL expressions. Therefore, if an attacker can inject arbitrary data in the error message template being passed, they will be able to run arbitrary Java code.CVE-2020-1961apachesyncope+16y ago04-05-2020 12:28

Vulnerability to Server-Side Template Injection on Mail templates for Apache Syncope 2.0.X releases prior to 2.0.15, 2.1.X releases prior to 2.1.6, enabling attackers to inject arbitrary JEXL expressions, leading to Remote Code Execution (RCE) was discovered.CVE-2020-11977apachesyncope+16y ago15-09-2020 19:02

In Apache Syncope 2.1.X releases prior to 2.1.7, when the Flowable extension is enabled, an administrator with workflow entitlements can use Shell Service Tasks to perform malicious operations, including but not limited to file read, file write, and code execution.CVE-2014-0111apachesyncope+112y ago17-04-2014 14:00

Apache Syncope 1.0.0 before 1.0.9 and 1.1.0 before 1.1.7 allows remote administrators to execute arbitrary Java code via vectors related to Apache Commons JEXL expressions, "derived schema definition," "user / role templates," and "account links of resource mappings."CVE-2014-3503apachesyncope+112y ago11-07-2014 14:00

Apache Syncope 1.1.x before 1.1.8 uses weak random values to generate passwords, which makes it easier for remote attackers to guess the password via a brute force attack.CVE-2024-38503apache software foundationapache syncope+32y ago22-07-2024 09:46

When editing a user, group or any object in the Syncope Console, HTML tags could be added to any text field and could lead to potential exploits. The same vulnerability was found in the Syncope Enduser, when editing “Personal Information” or “User Requests”. Users are recommended to upgrade to version 3.0.8, which fixes this issue.CVE-2024-45031apache software foundationapache syncope+21y ago24-10-2024 14:21

When editing objects in the Syncope Console, incomplete HTML tags could be used to bypass HTML sanitization. This made it possible to inject stored XSS payloads which would trigger for other users during ordinary usage of the application. XSS payloads could also be injected in Syncope Enduser when editing “Personal Information” or “User Requests”: such payloads would trigger for administrators in Syncope Console, thus enabling session hijacking. Users are recommended to upgrade to version 3.0.9, which fixes this issue.CVE-2019-17557apachesyncope+16y ago04-05-2020 12:27

It was found that the Apache Syncope EndUser UI login page prio to 2.0.15 and 2.1.6 reflects the successMessage parameters. By this mean, a user accessing the Enduser UI could execute javascript code from URL query string.CVE-2026-63071apache software foundationapache syncope+13mo ago20-07-2026 14:19

Improper Isolation or Compartmentalization vulnerability in Apache Syncope. An administrator with adequate entitlements for Implementations can create a malicious Groovy class containing untrusted code bypassing the Groovy security sandbox. This issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 through 4.0.6, from 4.1.0-M0 through 4.1.1. Users are recommended to upgrade to version 4.0.7 / 4.1.2, which fix this issue by tightening the Groovy security sandbox.CVE-2026-62418apache software foundationapache syncope+13mo ago20-07-2026 14:27

Low-privileged authenticated Server-Side Request Forgery (SSRF) vulnerability in Apache Syncope via Connectors and Resources check.

Improper Privilege Management vulnerability in Apache Syncope. When: * the all-Java user workflow adapter is configured, or * the Flowable user workflow adapter is configured, bearing a BPMN definition not requiring admin approval for user self registration of self update requests the following scenario could happen. A REST API call can allow the user to grant themselves one or more of defined Roles, thus gaining their Entitlements and becoming in fact an administrator; the actual Entitlements gained depend on the Roles that are effectively defined on the specific Syncope deployment. This issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 Through 4.0.6, from 4.1.0-M0 through 4.1.1. Users are recommended to upgrade to version 4.0.7 / 4.1.2, which fix this issue.CVE-2026-42782apache software foundationapache syncope+24mo ago25-05-2026 14:58

Improper Isolation or Compartmentalization vulnerability in Apache Syncope. An administrator with adequate entitlements for Implementations can create a malicious Groovy class containing untrusted code reaching a non-sandboxed execution path via the class static initializer. This issue affects Apache Syncope: 3.0 through 3.0.16, 4.0 through 4.0.5, 4.1.0. Users are recommended to upgrade to version 4.0.6 / 4.1.1, which fix this issue by forcing even the static initializer in Groovy code to run in a sandbox.CVE-2026-42797apache software foundationapache syncope+24mo ago25-05-2026 15:00

Exposure of Sensitive Information Through Data Queries vulnerability in Apache Syncope. An administrator with adequate entitlements for Derived Schemas can create a malicious JEXL expression which allows any administrator with sufficient entitlements for User read to access User-related security-sensitive information. This issue affects Apache Syncope: 3.0 through 3.0.16, 4.0 through 4.0.5, 4.1.0. Users are recommended to upgrade to version 4.0.6 / 4.1.1, which fix this issue by further restricting the JEXL expression definition.CVE-2026-53421apache software foundationapache syncope+13mo ago20-07-2026 14:21

Improper Isolation or Compartmentalization vulnerability in Apache Syncope. An administrator with adequate entitlements can achieve remote code execution through the connector subsystem by relying on scripted connectors' (REST and SQL) capability to run Groovy scripts. This issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 Through 4.0.6, from 4.1.0-M0 through 4.1.1.
