CVE-2026-33515 (GCVE-0-2026-33515)

Vulnerability from cvelistv5 – Published: 2026-03-26 00:13 – Updated: 2026-03-26 14:19

Title

Squid has issues in ICP message handling

Summary

Squid is a caching proxy for the Web. Prior to version 7.5, due to improper input validation, Squid is vulnerable to out of bounds read when handling ICP traffic. This problem allows a remote attacker to receive small amounts of memory potentially containing sensitive information when responding with errors to invalid ICP requests. This attack is limited to Squid deployments that explicitly enable ICP support (i.e. configure non-zero `icp_port`). This problem cannot be mitigated by denying ICP queries using `icp_access` rules. Version 7.5 contains a patch.

Severity

6.9 (Medium)

CVE-2026-47729 (GCVE-0-2026-47729)

Vulnerability from cvelistv5 – Published: 2026-07-16 16:13 – Updated: 2026-07-17 18:07

Title

Squid: Memory disclosure in FTP gateway

Summary

Squid is a caching proxy for the Web. Prior to 7.6, due to an improper validation of syntactic correctness of input in the FTP gateway (src/clients/FtpGateway.cc), Squid is vulnerable to an out-of-bounds read: when a listing entry date in the TypeA or TypeB directory-listing formats is not followed by a filename, parsing was not restricted to the input buffer, so a trusted client accessing a misbehaving FTP server through Squid's gateway feature could read memory from random unrelated transactions. This issue is fixed in version 7.6.

Severity

6.5 (Medium)

CVE-2026-50012 (GCVE-0-2026-50012)

Vulnerability from cvelistv5 – Published: 2026-07-16 16:11 – Updated: 2026-07-17 14:04

Title

Squid: Memory corruption in cache_digest reply handling

Summary

Squid is a caching proxy for the Web. Prior to 7.6, due to an improper input validation bug in cache digest reply handling (peerDigestSwapInMask in src/peer_digest.cc), Squid is vulnerable to a heap-based buffer overflow: a cache digest's on-the-wire size may be larger than the mask_size declared within the digest, so a trusted peer sending a maliciously crafted reply to a cache_digest request message can trigger the overflow. This attack is limited to Squid instances compiled with the --enable-cache-digests option and configured with cache_peer entries. This issue is fixed in version 7.6.

Severity

5.5 (Medium)
