CVE-2025-1300 | Open redirect in CodeChecker web server

CodeChecker is an analyzer tooling, defect database and viewer extension for the Clang Static Analyzer and Clang Tidy. The CodeChecker web server contains an open redirect vulnerability due to missing protections against multiple slashes after the product name in the URL.

Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
