Summary The isSSRFSafeURL function in AVideo can be bypassed using IPv4-mapped IPv6 addresses ::ffff:x.x.x.x. The unauthenticated plugin/LiveLinks/proxy.php endpoint uses this function to validate URLs before fetching them with curl, but the IPv4-mapped IPv6 prefix passes all checks, allowing an...

CVE-2026-30827: Allocation of Resources Without Limits or Throttling

express-rate-limit is a basic rate-limiting middleware for Express. In versions starting from 8.0.0 and prior to versions 8.0.2, 8.1.1, 8.2.2, and 8.3.0, the default keyGenerator in express-rate-limit applies IPv6 subnet masking /56 by default to all addresses that net.isIPv6 returns true for. Th...

The Jetty URI parser has some key differences compared to other common parsers when evaluating invalid or unusual URIs. Specifically: Invalid Scheme | URI | Jetty | uri-js nodejs | node-urlnodejs | |---|---|---| --- | | https://vulndetector.com/path | scheme=http| scheme=https | invalid URI |...

CVE-2026-27624

Coturn was vulnerable to a bypass of the IPv4-mapped IPv6 loopback/denied-peer-ip checks prior to 4.9.0. The root cause was that three functions in src/client/ns_turn_ioaddr.c did not check IN6_IS_ADDR_V4MAPPED, allowing a CreatePermission/ChannelBind with ::ffff:127.0.0.1 to bypass 127.0.0.0/8 l...

CVE-2026-26324 OpenClaw has a SSRF guard bypass via full-form IPv4-mapped IPv6 (loopback / metadata reachable)

OpenClaw is a personal AI assistant. Prior to version 2026.2.14, OpenClaw's SSRF protection could be bypassed using full-form IPv4-mapped IPv6 literals such as 0:0:0:0:0:ffff:7f00:1 which is 127.0.0.1. This could allow requests that should be blocked loopback / private network / link-local metada...
