ruby-mechanize: The Mechanize library is used for automating interaction with websites
CVE-2026-107715 is fixed in ruby-mechanize on 1 platform by DEBIAN-CVE-2026-107715 (version 2.14.1-1), released October 9, 2026. It is not reported as exploited. Patch Radar priority: Routine.
The Mechanize library is used for automating interaction with websites. Prior to 2.14.1, Mechanize sends caller-supplied credential headers to a different host after an HTTP redirect. Mechanize#request_headers= is reapplied by Mechanize::HTTP::Agent#request_add_headers even after Mechanize::HTTP::Agent#response_redirect strips per-request headers, and the protected header lists omit Proxy-Authorization and Cookie2. An attacker who controls a redirect target can capture bearer tokens or session cookies supplied through request_headers= or the per-request headers argument, while Mechanize#cookie_jar and Mechanize::HTTP::AuthStore are not affected. This issue is fixed in version 2.14.1.
