Exploitation evidence

Detectable: no evidence on record.
No public nuclei template indexed

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 2026-10-26.

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 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 18.11.3, 18.10.6 or 18.9.7.

AI-suggested

A patch is available and should be applied by upgrading GitLab EE to versions 18.9.7, 18.10.6, or 18.11.3 or later. Applying these official fixes will remediate the vulnerability. No additional mitigation steps are indicated by the vendor advisory.

Description

A cross-site scripting (XSS) vulnerability exists in GitLab EE versions from 16.4 up to but not including 18.9.7, 18.10 up to 18.10.6, and 18.11 up to 18.11.3. This flaw allows an authenticated user with developer-role permissions to execute arbitrary JavaScript in other users' browsers due to improper input sanitization. The issue has been remediated in the specified fixed versions.

Impact

An attacker with developer-role permissions could exploit this vulnerability to execute arbitrary JavaScript in other users' browsers, potentially leading to session hijacking, unauthorized actions, or data theft within the affected GitLab instance. The impact is limited to authenticated users with developer privileges and does not affect unauthenticated users.

Summary

GitLab EE contained an XSS vulnerability (CVE-2026-7481) affecting versions >=16.4.0 <18.9.7, >=18.10.0 <18.10.6, and >=18.11.0 <18.11.3. The vulnerability allowed authenticated users with developer permissions to inject and execute arbitrary JavaScript in the browsers of other users. This was caused by improper neutralization of input during web page generation. The vendor has released patches that fix this issue in versions 18.9.7, 18.10.6, and 18.11.3 respectively.
