Description
This security bulletin contains information about 2 vulnerabilities.
1) Cross-site request forgery (CVE-ID: CVE-2026-41425)
CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform cross-site request forgery and bind an attacker's account to a victim's session.
The vulnerability exists due to cross-site request forgery in OAuth integrations using the cache feature when handling OAuth callback requests with cached state. A remote attacker can send a crafted redirect URL to the victim to perform cross-site request forgery and bind an attacker's account to a victim's session.
User interaction is required for the victim to complete the authorization flow.
2) Open redirect (CVE-ID: CVE-2026-44681)
CWE-ID: CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:N/SC:L/SI:L/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to redirect users to an attacker-controlled URL.
The vulnerability exists due to url redirection to an untrusted site in OpenIDImplicitGrant and OpenIDHybridGrant authorization request validation when processing authorization requests that omit the openid scope. A remote attacker can send a specially crafted authorization request with an attacker-controlled redirect_uri to redirect users to an attacker-controlled URL.
Exploitation requires an authorization server deployment that registers the OIDC Implicit or Hybrid grant types, and user interaction is required.
