Description
This security bulletin contains information about 9 vulnerabilities.
1) Stored cross-site scripting (CVE-ID: CVE-2025-11224)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in k8s proxy. A remote user can inject and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
2) Incorrect authorization (CVE-ID: CVE-2025-11865)
CWE-ID: CWE-863 - Incorrect Authorization
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to bypass authorization checks.
The vulnerability exists due to incorrect authorization in workflows. A remote user can remove Duo flows of another user.
3) Information disclosure (CVE-ID: CVE-2025-6171)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application in packages API endpoint. A remote user can access the packages API endpoint even when repository access is disabled and view branch names and pipeline details.
4) Information disclosure (CVE-ID: CVE-2025-2615)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application in GraphQL subscriptions. A remote blocked user can establish GraphQL subscriptions through WebSocket connections and gain access sensitive information.
5) Information disclosure (CVE-ID: CVE-2025-7000)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application within access control. A remote user can access project issues with related merge requests and view confidential branch names.
6) Improper Validation of Generative AI Output (CVE-ID: CVE-2025-6945)
CWE-ID: CWE-1426 - Improper Validation of Generative AI Output
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the prompt injection issue in GitLab Duo review. A remote user can inject hidden prompts in merge request comments and leak sensitive information from confidential issues.
7) Path traversal (CVE-ID: CVE-2025-11990)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences in branch names. A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system.
8) Improper access control (CVE-ID: CVE-2025-7736)
CWE-ID: CWE-284 - Improper Access Control
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions in GitLab Pages. A remote user can bypass implemented security restrictions and view GitLab Pages content intended only for project members.
9) Input validation error (CVE-ID: CVE-2025-12983)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in markdown. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
