Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-47729 in the wild and no public exploit code.\n\nAffected product: Squid-Cache Squid. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-47729/ (Markdown: https://insights.sbomify.com/CVE-2026-47729/index.md)","id":"CVE-2026-47729","markdown":"https://insights.sbomify.com/CVE-2026-47729/index.md","name":"CVE-2026-47729","record":{"aliases":["ALPINE-CVE-2026-47729","AZL-92444","DEBIAN-CVE-2026-47729","GHSA-8c37-pxjq-qwrg","MINI-qhpm-mghr-w2gv","UBUNTU-CVE-2026-47729"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Web caching proxy","requires_auth":"low_privilege","summary":"A trusted client accessing a misbehaving FTP server via Squid's gateway can read memory from unrelated transactions due to improper input validation.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"squid","vendor":"squid-cache"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-1289","name":"Improper Validation of Unsafe Equivalence in Input"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"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.
