Exploitation evidence

Disclosed: evidence found.
CVE published 29 May 2024
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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 17.0.1, 16.11.3 or 16.10.6.

AI-suggested

A patch is available for this vulnerability. Users should upgrade affected GitLab versions to 16.10.6 or later for the 16.10.x branch, 16.11.3 or later for the 16.11.x branch, and 17.0.1 or later for the 17.0.x branch to remediate this issue.

Description

GitLab CE/EE versions from 13.2.4 before 16.10.6, 16.11 before 16.11.3, and 17.0 before 17.0.1 contain a vulnerability that allows denial of service (DoS) via crafted API calls exploiting improper handling of highly compressed data. This can cause service disruption.
