CWE-1389

Fedify is a TypeScript library for building federated server apps powered by ActivityPub. Fedify previously addressed SSRF/internal network access in GHSA-p9cg-vqcc-grcx by adding public URL validation before runtime document and media fetching. However, the IPv4 validation logic present starting in version 0.11.2 and prior to versions 1.9.12, 1.10.11, 2.0.19, 2.1.15, and 2.2.4 appears incomplete. The `validatePublicUrl()` protection relies on `isValidPublicIPv4Address()` to reject non-public IPv4 destinations. The function blocks common private and local ranges such as `10.0.0.0/8`, `127.0.0.0/8`, `169.254.0.0/16`, `172.16.0.0/12`, and `192.168.0.0/16`, but it still treats several special-use, reserved, multicast, benchmarking, and carrier-grade NAT IPv4 ranges as valid public destinations. Because this validation is used as an SSRF defense before outbound fetches, this appears to be an incomplete mitigation or bypass class for the previous SSRF issue. Versions 1.9.12, 1.10.11, 2.0.19, 2.1.15, and 2.2.4 contain an updated patch.

One Search 1.1.0.0 contains a denial of service vulnerability that allows local attackers to crash the application by submitting excessively long input strings to the search functionality. Attackers can paste a buffer of 950 or more characters into the search bar to trigger an unhandled exception that crashes the application.

In https://github.com/google/nftables  IP addresses were encoded in the wrong byte order, resulting in an nftables configuration which does not work as intended (might block or not block the desired addresses). This issue affects:  https://pkg.go.dev/github.com/google/nftables@v0.1.0 The bug was fixed in the next released version:  https://pkg.go.dev/github.com/google/nftables@v0.2.0

An incorrect parsing of numbers with different radices vulnerability [CWE-1389] in FortiProxy version 7.4.3 and below, version 7.2.10 and below, version 7.0.17 and below and FortiOS version 7.4.3 and below, version 7.2.8 and below, version 7.0.15 and below IP address validation feature may permit an unauthenticated attacker to bypass the IP blocklist via crafted requests.
