Deeper analysis AI-assisted summary

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

XWiki Platform is affected by CVE-2023-29526, a code injection flaw (CWE-74) that permits unauthorized display of or interaction with restricted pages. The root cause is insufficient isolation when the async and display macros are placed inside user comments; these macros are executed at view time in the context of the application server.

An authenticated user who can post comments can therefore leverage the macros to bypass access controls and obtain code execution privileges on the server, resulting in complete loss of confidentiality, integrity, and availability. The vulnerability carries a CVSS 3.1 score of 9.9 and is exploitable remotely with low attack complexity.

Public advisories hosted on GitHub and the XWiki Jira tracker state that the issue is resolved in XWiki 15.0-rc-1, 14.10.3, 14.4.8, and 13.10.11; administrators are advised to upgrade because no workarounds exist. The associated EPSS score has remained flat at 0.2251 with no material rise after disclosure.

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-74

Developer assessments and testing (including injection-focused techniques) identify improper neutralization of special elements, and the verifiable flaw remediation corrects them pre-deployment.

addresses: CWE-74

Identifies indicators of injection attacks (command, SQL, LDAP, etc.) via anomaly and attack monitoring.
