CVE-2022-2865 is a high-severity cross-site scripting (XSS) vulnerability discovered in GitLab CE/EE. This issue affects all versions before 15.1.6, versions 15.2 to 15.2.4, and versions 15.3 prior to 15.3.2. The vulnerability arises from a flaw in the feature that allows users to set label colors, leading to a potential stored XSS attack. Attackers may leverage this vulnerability to perform arbitrary actions on behalf of victims at the client side.
The severity level of this vulnerability is classified as high, with a CVSS score of 7.3. This score indicates a significant risk to organizations, especially considering the potential for attackers to exploit the XSS vulnerability in a networked environment.
The risk to organizations includes unauthorized actions being performed in the context of authenticated users, potentially leading to data breaches or further exploitation within the application. Organizations should prioritize patching immediately to mitigate these risks.
Currently, there are no public exploits confirmed for this vulnerability, but its high severity warrants immediate attention. Organizations should ensure they are using patched versions of GitLab to protect against potential exploitation.
As of the latest updates, the vulnerability status is marked as modified, reflecting ongoing attention and updates from the GitLab team.
To effectively defend against this vulnerability, organizations must adopt a proactive approach towards security updates and vulnerability management.
Vulnerability Details
The official description of CVE-2022-2865 states that a cross-site scripting issue has been discovered in GitLab CE/EE affecting all versions before 15.1.6, 15.2 to 15.2.4, and 15.3 prior to 15.3.2. This vulnerability allows attackers to exploit a flaw in the settings of the labels color feature, leading to a stored XSS vulnerability.
The CVSS score of this vulnerability is 7.3, indicating a high severity. The attack vector is classified as network-based, and the attack complexity is high, requiring significant privileges and user interaction. The confidentiality and integrity impacts are rated high, while availability is rated as none.
The affected products are GitLab CE and EE, specifically versions noted above. The CVE was published on October 17, 2022.
Technical Analysis
The root cause of this vulnerability lies in the insufficient validation of user input when setting label colors. This allows crafted inputs to be stored in the application, which can then be executed in the context of a user session, leading to arbitrary JavaScript execution.
The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely. The complexity is rated high due to the requirement for elevated privileges and user interaction, as the victim must click on the malicious content to trigger the attack. Additionally, this vulnerability requires a high level of privilege to exploit, limiting the potential attackers.
The impacts of this vulnerability are significant, with high confidentiality and integrity impacts indicating that sensitive data may be compromised, and unauthorized actions performed under the guise of the victim's permissions.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2022-2865 is considerable. Organizations that utilize vulnerable versions of GitLab are exposed to potential exploitation that could lead to unauthorized access to sensitive data or control over user accounts.
Given the nature of the vulnerability, the blast radius can be extensive, especially in environments where GitLab is used for critical development and deployment processes. The urgency assessment is high, as the CVSS score reflects a significant risk that must be addressed promptly.
Organizations should prioritize remediation efforts and ensure that their installations of GitLab are updated to the latest secure versions to mitigate the risks associated with this vulnerability.

Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The versions affected by CVE-2022-2865 include all GitLab CE/EE versions prior to 15.1.6, along with versions 15.2 to 15.2.4 and 15.3 prior to 15.3.2. Organizations running these versions are at risk and should upgrade to the latest patched version.
Mitigation & Remediation
Organizations should prioritize patching immediately by upgrading to GitLab versions 15.1.6 or later, or any version beyond the specified vulnerable releases. In cases where immediate patching is not feasible, workarounds should be implemented, including disabling the label color feature if possible.
For comprehensive security, organizations are encouraged to adopt a robust vulnerability management program. Additional measures, such as configuration hardening and network controls, can further reduce exposure to such vulnerabilities. Regular security assessments, including application security assessments, should be conducted to identify and mitigate similar weaknesses.
Detection Guidance
To monitor for exploitation attempts related to CVE-2022-2865, organizations should implement logging for user actions specific to label settings. Behavioral anomalies, such as unusual label color changes or unexpected user activity, should be flagged for review. Network signatures that detect unauthorized access attempts can also aid in identifying potential exploitation.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2022-2865 highlights the critical need for security teams to prioritize user input validation across all applications. This vulnerability exemplifies the potential for XSS attacks in widely used collaboration tools, which can have significant organizational impact.
Organizations should learn from this incident and enhance their security postures by implementing comprehensive security testing processes, such as penetration testing and continuous monitoring of web applications.
In conclusion, CVE-2022-2865 serves as a reminder that security practices must evolve alongside application development. Staying informed about vulnerabilities and threats is vital in maintaining a robust defense against potential exploitation.
