An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-26307 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.25.5\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.25.5\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.25.5\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-2026-26307/ (Markdown: https://insights.sbomify.com/CVE-2026-26307/index.md)","id":"CVE-2026-26307","markdown":"https://insights.sbomify.com/CVE-2026-26307/index.md","name":"CVE-2026-26307","record":{"aliases":["GHSA-h9c5-x7g8-4q7f","GO-2026-6341"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Git server","requires_auth":"none","summary":"Attackers can cause denial of service by triggering expensive git grep searches that consume server resources due to missing timeouts.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gitea","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Gitea versions before 1.25.5 do not enforce a timeout on git grep searches, allowing expensive searches to consume server resources.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Gitea git grep search lacks a timeout","id":"CVE-2026-26307","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":"Envoy has an RBAC Header Validation Bypass via Multi-Value Header Concatenation","id":"CVE-2026-26308"},"packages":[{"ecosystem":"Go","fixed":["1.25.5"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":null,"source":"GHSA-h9c5-x7g8-4q7f"},{"ecosystem":"Go","fixed":["1.25.5"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GHSA-h9c5-x7g8-4q7f"},{"ecosystem":"Go","fixed":["1.25.5"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GO-2026-6341"}],"prev":{"headline":"Other in OM Workspace (Windows Edition)","id":"CVE-2026-26306"},"products":["Gitea Open Source Git Server"],"published":"2026-07-03","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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-09","vendors":["Gitea"]},"summary":"Attackers can cause denial of service by triggering expensive git grep searches that consume server resources due to missing timeouts.","url":"https://insights.sbomify.com/CVE-2026-26307/"}
