Deeper analysis AI-assisted summary

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

PMB version 7.4.6 contains an open redirect vulnerability in the /opac_css/pmb.php component. The flaw, tracked as CVE-2023-24735 and assigned CWE-601, permits an attacker to supply a crafted URL that causes the application to redirect users to an arbitrary external domain. The issue received a CVSS 3.1 score of 6.1, reflecting network attack vector, low complexity, no required privileges, and required user interaction with changed scope.

An unauthenticated attacker can exploit the vulnerability by delivering a malicious link to a victim; if the victim follows the link, the browser is redirected to an attacker-controlled site, enabling phishing or further attacks against the redirected user. The two referenced GitHub repositories provide proof-of-concept details but contain no official vendor advisory or patch information.

EPSS scores for the CVE reached a peak of 0.0948 and currently stand at 0.0712, indicating modest and stable exploitation interest since disclosure.
