Exploitation evidence

CVE published 16 Jul 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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 18.0.1.

AI-suggested

Apply the official patches by upgrading GitLab CE/EE to versions 17.11.6 or later, 18.0.4 or later, and 18.1.2 or later. These updates address the cross-site scripting vulnerability. No additional mitigation steps are required once patched.

Description

A cross-site scripting (XSS) vulnerability exists in GitLab CE/EE versions from 17.11 before 17.11.6, 18.0 before 18.0.4, and 18.1 before 18.1.2. This flaw could allow an attacker to inject malicious content and execute actions on behalf of users under certain conditions. The vulnerability is classified as high severity. A patch is available to address this issue.

Impact

Successful exploitation could allow an attacker to perform actions on behalf of authenticated users by injecting malicious scripts into web pages. This can lead to unauthorized actions within the GitLab environment, potentially compromising user accounts or data integrity.

Summary

CVE-2025-6948 is a cross-site scripting vulnerability in GitLab CE/EE affecting all versions from 17.11 before 17.11.6, 18.0 before 18.0.4, and 18.1 before 18.1.2. The vulnerability arises from improper neutralization of input during web page generation, enabling attackers to inject malicious content that could execute actions on behalf of users. This issue has been patched in the specified fixed versions.
