bind: bind9: Cache poisoning via label count discrepancy, RRSIG, wildcards

It is possible for an attacker's zone to respond to a query with an RRSIG that has a smaller number of labels than the zone in which the RRSIG is contained. This causes named to produce a wildcard name for a zone that is shorter than the attacker's zone, which can result in cache poisoning. For...

CVE-2026-117666

A flaw was found in sslverifyfun. The library improperly validates Transport Layer Security TLS certificates containing partial wildcards, allowing wildcard patterns to match across domain label boundaries and IP addresses. A man-in-the-middle attacker can exploit this vulnerability by presenting...

CVE-2026-116821 YesWiki before 4.7.0 Read-ACL Bypass via SQL LIKE Wildcards in Usernames

YesWiki before 4.7.0 contains a read-ACL bypass in AclService::updateRequestWithACL, which interpolates usernames into SQL LIKE patterns without escaping the and % wildcards. Self-registered attackers can use usernames such as or %%% that over-match ACL tokens, reading pages and Bazar entries...

CVE-2026-116821

YesWiki versions prior to 4.7.0 are vulnerable to a read-ACL bypass in the AclService::updateRequestWithACL function. The root cause is the failure to escape _ and % wildcards when interpolating usernames into SQL LIKE patterns . An attacker with self-registration capabilities can use specific us...

BIT-RABBITMQ-2026-67419 RabbitMQ: Consecutive topic wildcards cause combinatorial routing work

RabbitMQ is a messaging and streaming broker. Prior to 4.3.5, an authenticated user who can bind a queue to a topic exchange and publish to it can use consecutive segments in a binding key to make both topic matchers revisit the same trie-node and routing-key-suffix states without memoization. Th...
