Author account gives PR:L; needing an includable local .php file is an attack requirement modeled as AC:H; successful inclusion yields full host code execution, so C/I/A:H.

DescriptionCVE.org

Emlog is an open source website building system. In 2.6.13 and earlier, the article publishing interface stores a path-traversal template parameter from api_controller.php without validation, and log_controller.php later checks file_exists and calls include View::getView($template), allowing an authenticated author to include an arbitrary local .php file when an article is viewed. No fixed version is currently identified.

AnalysisAI

Local file inclusion in Emlog 2.6.13 and earlier lets an authenticated author supply a path-traversal template value that is stored unvalidated by api_controller.php and later passed to View::getView() in log_controller.php, causing an arbitrary local .php file to be included when the article is viewed. Because included PHP is executed, an attacker who can place or influence a .php file on the host can escalate this to code execution. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated account with the author (publishing) role, because the malicious template value is injected via the article-publishing interface in api_controller.php. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The vendor CVSS 4.0 vector (AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H, base 7.7) describes a network-reachable but privileged and conditional attack: PR:L requires a valid author account, and AT:P signals that specific attack requirements must be met - here, referencing an existing includable local .php file, since the primitive only includes local files. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker holding (or registering/phishing) an Emlog author account publishes an article and sets the template parameter to a traversal path such as '../../uploads/evil.php', paired with any avenue that lets them drop a .php file on the host. When the article is viewed, log_controller.php passes the path to View::getView() and include() executes the attacker's PHP, yielding code execution. …
Remediation No vendor-released patch identified at time of analysis and no fixed version is named, so upgrade is not yet possible; monitor advisory GHSA-9h6g-q584-9vfg (https://github.com/emlog/emlog/security/advisories/GHSA-9h6g-q584-9vfg) for a patched release. … Detailed patch versions, workarounds, and compensating controls in full report.
