Exploitation Conditions

No special conditions are required beyond network access to the phpMyFAQ PDF export endpoint. The CVSS 4.0 vector AV:N/AC:L/AT:N/PR:N/UI:N confirms exploitation is possible remotely by unauthenticated attackers against default-configured installations. The attack surface is the publicly accessible PDF export route - a default feature of phpMyFAQ deployments intended to serve end users. Exploitation is bounded by the sensitivity of draft FAQ content stored in the instance: organizations whose drafts contain only benign content face lower effective risk. Impact is limited to metadata (titles, solution IDs, author names, timestamps) and does not extend to full FAQ body text, authentication credentials, or underlying system data. No non-default configuration is required to be vulnerable.

Impact

The CVSS 4.0 base score of 6.9 reflects AV:N/AC:L/AT:N/PR:N/UI:N, confirming the vulnerability is trivially reachable over the network with no preconditions, yet the confidentiality impact is bounded to VC:L with no integrity or availability consequence, capping real damage to metadata disclosure. EPSS data is not available in the provided intelligence, so probabilistic exploitation likelihood cannot be quantified. The absence of a CISA KEV listing and no referenced POC code suggest exploitation has not been observed in the wild. In practical terms, even a mid-sized municipal IT team in mielec running phpMyFAQ to manage public-service FAQs should treat this as a low-urgency but non-trivial remediation task - particularly if draft entries contain sensitive organizational content such as unreleased policy language or internal author identities. The real-world risk is primarily information leakage enabling pre-attack reconnaissance or reputational exposure from leaked draft content, not system compromise.

Exploit ScenarioDerived

An unauthenticated attacker identifies a publicly accessible phpMyFAQ instance and submits HTTP GET requests to the PDF export endpoint using sequential integer FAQ identifiers. For each draft or inactive FAQ in the database, the endpoint returns metadata including the entry title, solution ID, author name, and last-update timestamp, allowing the attacker to reconstruct the unpublished content inventory without credentials or specialized tooling.

AnalysisAIv1 – Aug 19, 2026

phpMyFAQ before version 4.1.7 fails to validate the active/published status of FAQ entries in its PDF export endpoint, enabling unauthenticated remote attackers to retrieve metadata for draft and unpublished FAQ items. By iterating sequential FAQ identifiers against the publicly accessible PDF export route, an attacker can harvest titles, solution IDs, author names, and last-update timestamps of content not yet approved for public release. No public exploit code or active exploitation has been identified at time of analysis, and no CISA KEV listing exists for this vulnerability.

RemediationAI

The primary fix is to upgrade phpMyFAQ to version 4.1.7 or later, as confirmed by the vendor advisory at https://github.com/thorsten/phpMyFAQ/security/advisories/GHSA-f8pr-32pp-mp7h. If immediate upgrade is not feasible, a compensating control is to restrict access to the PDF export endpoint at the web server or reverse proxy layer - for example by requiring session-based authentication or enforcing IP allowlisting before requests reach the application. This trade-off reduces exposure of draft content but degrades the usability of the public export feature for legitimate users. Blocking the endpoint entirely eliminates the risk while disabling PDF export functionality for all users. No additional vendor-endorsed workarounds are referenced in the available advisory data.

Technical ContextAI · show details

phpMyFAQ is an open-source, PHP-based FAQ management application developed by Thorsten Rinne that implements a publication workflow distinguishing between draft and active FAQ entries. The vulnerability arises because the PDF export endpoint does not enforce active-status validation before rendering entry metadata, constituting a CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) root cause - the application exposes data through a legitimate public access channel that bypasses the authorization logic applied in other parts of the application. The affected product is identified by CPE cpe:2.3:a:thorsten:phpmyfaq:*:*:*:*:*:*:*:*, covering all releases prior to 4.1.7. Because the PDF export route is designed to be publicly accessible, the missing status filter is particularly exploitable with no authentication barrier whatsoever.

DescriptionCVE.org

phpMyFAQ versions before 4.1.7 fail to validate active status in the PDF export endpoint, allowing unauthenticated attackers to retrieve draft FAQ metadata. Attackers can access the public PDF export route with sequential FAQ identifiers to obtain titles, solution IDs, author names, and last-update timestamps of inactive or unpublished FAQs.
