Leantime contains an OIDC login CSRF vulnerability in the verifyState method that unconditionally returns true without validating state parameters. Attackers can craft malicious callback URLs with attacker-controlled authorization codes to perform session fixation, logging victims in as the...

GHSA-9R87-MVCW-X35F Coder vulnerable to OIDC account takeover via email-based user matching and email_verified bypass

Summary Two flaws in Coder's OIDC login chained into account takeover: email-based user matching fell back to linking by email without checking for an existing link to a different IdP subject and the emailverified claim was only enforced when present as a boolean false so an absent or non-boolean...

When an IdP returned the claim as a non-boolean for example the string "false" or omitted it, the assertion failed open and the email was treated as verified. Combined with an unconditional email-based accou...
