CVE-2026-30993
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSlah CMS v1.5.0 and below was discovered to contain a remote code execution (RCE) vulnerability in the session() function at config.php. This vulnerability is exploitable via a crafted input.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceSlah CMS versions 1.5.0 and below contain a remote code execution vulnerability in the session() function within config.php. The vulnerability is exploitable through crafted input, allowing an attacker to execute arbitrary code on the affected system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Slah CMS installationLocate the Slah CMS installation directory and find the main application files (typically in the web root). Look for config.php and other core CMS files.Affected if The system has Slah CMS installed
-
Check installed Slah CMS versionOpen the main CMS file (such as index.php, version.php, or a configuration file) to find the version number. Alternatively, check any version metadata file that may exist in the installation.Affected if The installed version is 1.5.0 or lower
-
Locate the vulnerable config.phpNavigate to the config.php file within the Slah CMS installation directory.Affected if config.php exists in the CMS installation
-
Inspect the session() function in config.phpOpen config.php and locate the session() function definition and its calls. Examine whether the function processes user-supplied input without validation.Affected if The session() function in config.php processes unchecked user input
-
Check for exposed session input vectorsReview how session data is handled - examine if $_SESSION, $_POST, $_GET, or $_COOKIE values are passed directly to the session() function without sanitization.Affected if User-controllable data (from GET, POST, COOKIE, or session parameters) flows into the session() function without validation
The system is affected if Slah CMS version 1.5.0 or below is installed and the session() function in config.php processes unsanitized user input.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade Slah CMS to a version beyond 1.5.0 that addresses this vulnerability, or implement input validation/sanitization on the session() function in config.php to prevent malicious input from being processed.
