Summary

CVE-2023-1178 is a medium-severity Code Injection (CWE-94) vulnerability in Gitlab Gitlab. Its CVSS base score is 5.7 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 41% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

GitLab CE/EE contains a vulnerability in all versions from 8.6 before 15.9.6, all versions from 15.10 before 15.10.5, and all versions from 15.11 before 15.11.1. The flaw permits file integrity to be compromised when source code or installation packages are pulled from a tag or release that contains a reference to another commit, and it is tracked under CWE-94 with a CVSS 3.1 score of 5.7.

An authenticated attacker with low privileges can exploit the issue by creating or manipulating a tag or release that points to an alternate commit. Successful exploitation allows the attacker to cause users or automated processes that fetch the tagged content to receive altered files, affecting integrity while requiring user interaction and presenting no impact to confidentiality or availability.

Public references direct practitioners to GitLab's CVE record and associated issue tracker for patch information; fixes are included in the versions that remediate the affected release lines.

EPSS remains low and stable near 0.09 with no material post-disclosure rise.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-94

Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.

addresses: CWE-94

Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.

addresses: CWE-94

Validates inputs used in dynamic code generation to block injected directives.

addresses: CWE-94

Directly prevents execution of attacker-supplied code written into data memory regions.

PR.PS-06 mostly match
blocks

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
blocks

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.
