CVE-2026-58425 affects Gitea’s OAuth 2.0 token introspection endpoint. The issue arises in IntrospectOAuth: after authenticating the introspecting client, the code rebinds app to the grant’s issuing application and populates the response from that app, effectively disclosing token metadata for an...

netty: Netty: High integrity impact due to improper DNS domain name constraint enforcement

A flaw was found in Netty. Netty's DNS Domain Name System codec does not properly enforce domain name constraints as defined in RFC 1035 during both encoding and decoding processes. This vulnerability allows a remote attacker to exploit the decoder using malicious DNS responses or exploit the...

CVE-2026-73212 coturn peer-IP ACL canonicalization & scope bypass on the RFC 6062 TCP CONNECT relay path → internal-network SSRF and proven internal root RCE

Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.13.1, goodpeeraddr in src/server/nsturnserver.c uses ioaaddrinrange in src/client/nsturnioaddr.c without canonicalizing IPv4-compatible, 6to4, and 64:ff9b::/96 NAT64 address forms, allowing an authenticated RFC 6062 T...

CVE-2026-68118

The CVE-2026-68118 issue affects the Linux kernel TCP stack: the SYN-RECEIVED path tcp_check_req() accepted in-window non-exact RSTs without exact SEG.SEQ match, causing the request to be removed instead of issuing a challenge ACK. The fix enforces RFC 9293/5961 order by applying the RST check be...
