Summary

CVE-2024-7008 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Calibre-Ebook Calibre. Its CVSS base score is 5.4 (Medium).

Operationally, ranked in the top 5.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

Calibre versions up to and including 7.15.0 contain a reflected cross-site scripting vulnerability (CWE-79) caused by insufficient sanitization of user-supplied input. The flaw received a CVSS 3.1 score of 5.4 and affects the application's handling of web content rendered in the browser.

An unauthenticated remote attacker can exploit the issue by crafting a malicious link or request that is opened by a victim user, resulting in execution of arbitrary script in the context of the Calibre web interface. Successful exploitation allows limited reading and modification of data accessible to that interface but does not directly impact availability.

The referenced GitHub commit (863abac) implements input sanitization to close the vector, and the StarLabs advisory provides technical details for affected deployments. Administrators should upgrade to a version containing the fix. The associated EPSS score has reached a peak of 0.1633, indicating moderate and sustained exploitation interest following disclosure.
