A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade gitlab to 17.1.1, 17.0.3 or 16.11.5.

AI-suggested

A patch is available for this vulnerability. Users should upgrade GitLab to versions 16.11.5 or later, 17.0.3 or later, or 17.1.1 or later to remediate this issue. Applying these official fixes will prevent exploitation of the stored XSS vulnerability.

Description

A stored cross-site scripting (XSS) vulnerability exists in GitLab Community and Enterprise Editions. The flaw affects versions from 16.9 up to but not including 16.11.5, 17.0 up to but not including 17.0.3, and 17.1 up to but not including 17.1.1. The vulnerability arises when malicious commit notes are imported into a project, allowing injection of malicious scripts during web page generation.

Impact

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the victim's browser session when viewing affected project pages. This could lead to session hijacking, defacement, or other malicious actions within the scope of the user's permissions. There are no known exploits in the wild at this time.

Summary

CVE-2024-4901 is a stored XSS vulnerability in GitLab CE/EE. It affects all versions starting from 16.9 prior to 16.11.5, from 17.0 prior to 17.0.3, and from 17.1 prior to 17.1.1. The issue occurs because input from commit notes imported into a project is not properly neutralized during web page generation, enabling attackers to inject malicious scripts that persist and execute in users' browsers.
