## Technical details

A remote code execution vulnerability exists in SIGB PMB v8.0.1.14 within the 'opac_css/cms_rest.php' component. The flaw stems from the insecure deserialization (CWE-502) of untrusted data from an arbitrary file. A remote, unauthenticated attacker can trigger this vulnerability by sending a crafted request to the affected endpoint, leading to arbitrary code execution in the context of the web server.
