Package	Ecosystem	Affected	Fixed in
github.com/dexidp/dex	Go	>=2.37.0, <2.38.0 \|\| <0.0.0-20240125115555-5bbdb4420254	2.38.0, 0.0.0-20240125115555-5bbdb4420254

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Dex versions from 2.37.0 before 2.38.0, and development builds before 0.0.0-20240125115555-5bbdb4420254, ignore the configured TLS settings when serving HTTPS, so deprecated TLS 1.0 and TLS 1.1 and the configured cipher suites are not enforced. An attacker who can intercept network traffic to Dex could decrypt connections made over these older protocols. Upgrade to Dex 2.38.0 or to 0.0.0-20240125115555-5bbdb4420254 or later. The source gives few details on the exact conditions required for interception.
