Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-45440 affects core/authorize.php in Drupal 11.x-dev and enables full path disclosure even when error logging is set to None. The flaw is triggered when the hash_salt value is obtained via file_get_contents on a file that does not exist. It is tracked as CWE-209 with a CVSS 3.1 score of 5.3 reflecting network-accessible information disclosure.

Unauthenticated remote attackers can exploit the condition without credentials or user interaction to obtain limited file-system path details that may support further reconnaissance against the affected Drupal instance.

The EPSS score reached a peak of 0.8754 with a current value of 0.8669. Public references include the Drupal issue tracker, an Exploit-DB entry, and a technical analysis at senscybersecurity.nl.
