Machine-written summary

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

Keycloak (org.keycloak:keycloak-services) versions before 26.2.2 are affected. The source describes a flaw where setting the verification policy to 'ANY' skips trust store certificate verification, which is unintended. The source gives few details about the attack conditions or impact. Upgrade to version 26.2.2 or later; no workaround is listed.
