An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-52814 exists.\n\nAffected packages and fixed versions:\n- gogs.io/gogs (Go): affected all versions; no fix listed\n- gogs.io/gogs (Go): affected all versions; fixed in 0.14.3\n- gogs.io/gogs (Go): affected all versions; fixed in 0.14.3\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-2026-52814/ (Markdown: https://insights.sbomify.com/CVE-2026-52814/index.md)","id":"CVE-2026-52814","markdown":"https://insights.sbomify.com/CVE-2026-52814/index.md","name":"CVE-2026-52814","record":{"aliases":["GHSA-xp79-5mx3-jx52","GO-2026-5765"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Self-hosted Git service","requires_auth":"none","summary":"Unauthenticated attackers can exhaust file descriptors by stalling SSH handshakes, causing denial of service for legitimate users.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Gogs is an open source self-hosted Git service. Prior to 0.14.3, the Gogs built-in Go SSH server is vulnerable to an unauthenticated, asymmetric Denial of Service (DoS) attack. The application accepts inbound TCP connections and passes them to golang.org/x/crypto/ssh.NewServerConn inside a new goroutine without enforcing any read/write deadlines on the underlying net.Conn. An unauthenticated attacker can open multiple TCP connections to the SSH port and simply withhold the SSH protocol banner. This forces the server to spawn an unbounded number of goroutines that block indefinitely waiting for socket I/O. This leads to complete File Descriptor (FD) exhaustion, preventing legitimate users from accessing the Git SSH service, and ultimately destabilizing the entire Gogs process (e.g., causing internal log rotation failures). This vulnerability is fixed in 0.14.3.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Gogs: Unauthenticated Asymmetric Denial of Service (DoS) via SSH Handshake Stall (File Descriptor Exhaustion)","id":"CVE-2026-52814","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":3,"n_references":4,"next":{"headline":"Gogs: Unauthenticated Organization Teams Information Disclosure via API","id":"CVE-2026-52815"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"gogs.io/gogs","purl":"pkg:golang/gogs.io/gogs","source":"GO-2026-5765"},{"ecosystem":"Go","fixed":["0.14.3"],"introduced":["0"],"last_affected":[],"package":"gogs.io/gogs","purl":null,"source":"GHSA-xp79-5mx3-jx52"},{"ecosystem":"Go","fixed":["0.14.3"],"introduced":["0"],"last_affected":[],"package":"gogs.io/gogs","purl":"pkg:golang/gogs.io/gogs","source":"GHSA-xp79-5mx3-jx52"}],"prev":{"headline":"Gogs: Path Traversal in organization name results in RCE through Git hooks","id":"CVE-2026-52813"},"products":["gogs"],"published":"2026-06-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-25","vendors":["gogs"]},"summary":"Unauthenticated attackers can exhaust file descriptors by stalling SSH handshakes, causing denial of service for legitimate users.","url":"https://insights.sbomify.com/CVE-2026-52814/"}
