DescriptionCVE.org

phpMyFAQ before 4.1.7 fails to apply parent FAQ visibility checks before returning child resources including comments and attachments. Unauthenticated attackers can retrieve restricted comment text, commenter email addresses, and attachment filenames for FAQ records they cannot directly access by querying the comments and attachments API endpoints.

AnalysisAI

Missing authorization in phpMyFAQ before 4.1.7 exposes restricted FAQ child resources - comments and attachments - to unauthenticated network attackers via unguarded API endpoints. The system applies visibility restrictions to parent FAQ records but omits equivalent checks when those records' associated comments and attachments are queried directly, leaking comment text, commenter email addresses, and attachment filenames. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the target phpMyFAQ instance has at least one FAQ record configured with restricted visibility that also has one or more associated comments or attachments. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N) accurately captures the risk profile: fully unauthenticated, network-reachable, low-complexity exploitation with a limited confidentiality impact and no integrity or availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated attacker discovers a phpMyFAQ instance and iterates numeric IDs against the /api/v2.0/comments and /api/v2.0/attachments endpoints. Even though the parent FAQ records carrying those IDs are configured as restricted and return an access-denied response when accessed directly, the child-resource endpoints return full payloads including comment text, commenter email addresses, and attachment filenames. …
Remediation Upgrade phpMyFAQ to version 4.1.7 or later, which is the vendor-confirmed patched release per the GitHub Security Advisory GHSA-jmv9-23mw-mxpq. … Detailed patch versions, workarounds, and compensating controls in full report.
