Security readout for executives and security teams
Plain-English summary
Pimcore logged cookie and server environment data into an HTTP error log. That can expose sensitive values such as database passwords and session cookies to anyone able to retrieve the log through the Pimcore backend. Pimcore fixed this in versions 12.3.1 and 11.5.14.
Executive priority
Treat as high priority for Pimcore environments. The main business risk is credential or session exposure from logs, which can enable follow-on compromise. Patch promptly and verify whether secrets were logged.
Technical view
CVE-2026-23493 is a CWE-532 sensitive information exposure in Pimcore before 12.3.1 and 11.5.14. The http_error_log stored $_COOKIE and $_SERVER variables, potentially leaking secrets and session data. The CVSS 3.1 score is 8.6 with high confidentiality impact.
Likely exposure
Organizations running Pimcore 12.0.0-RC1 through before 12.3.1, or any version before 11.5.14, are potentially exposed if the backend can access the affected log file.
Exploitation context
The source bundle does not show CISA KEV listing or public active exploitation. Risk depends on backend log accessibility and whether sensitive environment variables or cookies were written before patching.
Researcher notes
The record identifies logging of $_COOKIE and $_SERVER into http_error_log and backend recoverability. Public sources provided do not include exploit details or observed exploitation. The fix is represented by Pimcore advisory, pull request, commit, and releases 11.5.14 and 12.3.1.
Mitigation direction
- Upgrade Pimcore 12.x deployments to 12.3.1 or later.
- Upgrade Pimcore 11.x deployments to 11.5.14 or later.
- Review vendor advisory and release notes for deployment-specific guidance.
- Restrict backend and log access to trusted administrators only.
- Rotate database passwords or session-related secrets found in affected logs.
Validation and detection
- Inventory Pimcore versions across production and staging systems.
- Confirm deployments are at 12.3.1, 11.5.14, or later.
- Check whether http_error_log exists and contains sensitive values.
- Review backend permissions for access to logs.
- Document any exposed secrets and confirm they were rotated.

Insertion of Sensitive Information into Log File
Insertion of Sensitive Information into Log File represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
