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 18.2.1, 18.1.3 or 18.0.5.

AI-suggested

A patch is available and users should upgrade to GitLab versions 18.0.5, 18.1.3, 18.2.1 or later to remediate this vulnerability. Applying these official fixes will mitigate the risk of exploitation.

Description

A cross-site scripting (XSS) vulnerability exists in GitLab CE/EE versions from 15.10 up to but not including 18.0.5, from 18.1 up to but not including 18.1.3, and from 18.2 up to but not including 18.2.1. Under specific conditions, this flaw could allow an attacker to cause unintended content rendering in web pages. This issue has been addressed in the indicated fixed versions.

Impact

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected GitLab web application, potentially leading to session hijacking, defacement, or other malicious actions within the scope of the user's browser session. However, no known exploits in the wild have been reported.

Summary

CVE-2025-4700 is a cross-site scripting vulnerability in GitLab CE/EE affecting versions >=15.10.0 <18.0.5, >=18.1.0 <18.1.3, and >=18.2.0 <18.2.1. The vulnerability arises from improper neutralization of input during web page generation, which could allow an attacker to trigger unintended content rendering leading to XSS. This could be exploited under specific circumstances. A patch is available in versions 18.0.5, 18.1.3, and 18.2.1 and later.
