An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-45328 exists.\n\nAffected packages and fixed versions:\n- github.com/go-gitea/gitea (Go): affected all versions; fixed in 1.4.3\n- github.com/go-gitea/gitea (Go): affected all versions; fixed in 1.4.3\n- github.com/go-gitea/gitea (Go): affected all versions; fixed in 1.4.3\n- gitea (Bitnami): affected all versions; fixed in 1.4.3\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-2021-45328/ (Markdown: https://insights.sbomify.com/CVE-2021-45328/index.md)","id":"CVE-2021-45328","markdown":"https://insights.sbomify.com/CVE-2021-45328/index.md","name":"CVE-2021-45328","record":{"aliases":["BIT-gitea-2021-45328","GHSA-36h2-95gj-w488","GO-2022-0579","UBUNTU-CVE-2021-45328"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Gitea Git service","requires_auth":"none","summary":"Attackers can redirect users to untrusted sites via internal URLs in Gitea, potentially facilitating phishing attacks.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"gitea","vendor":"gitea"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"Gitea before 1.4.3 is affected by URL Redirection to Untrusted Site ('Open Redirect') via internal URLs.","ecosystems":["Bitnami","Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-45328.yaml","stars":null,"title":"Gitea \u003c 1.4.3 - Open Redirect"}],"tier":"weaponised"},"has_fix":true,"headline":"Open redirect in Gitea","id":"CVE-2021-45328","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"gitea:gitea","products":["gitea:gitea"],"type":"open_redirect","year":"2021"},"n_packages":4,"n_references":2,"next":{"headline":"Cross-site Scripting in Gitea","id":"CVE-2021-45329"},"packages":[{"ecosystem":"Bitnami","fixed":["1.4.3"],"introduced":["0"],"last_affected":[],"package":"gitea","purl":"pkg:bitnami/gitea","source":"BIT-gitea-2021-45328"},{"ecosystem":"Go","fixed":["1.4.3"],"introduced":["0"],"last_affected":[],"package":"github.com/go-gitea/gitea","purl":null,"source":"GHSA-36h2-95gj-w488"},{"ecosystem":"Go","fixed":["1.4.3"],"introduced":["0"],"last_affected":[],"package":"github.com/go-gitea/gitea","purl":"pkg:golang/github.com/go-gitea/gitea","source":"GHSA-36h2-95gj-w488"},{"ecosystem":"Go","fixed":["1.4.3"],"introduced":["0"],"last_affected":[],"package":"github.com/go-gitea/gitea","purl":"pkg:golang/github.com/go-gitea/gitea","source":"GO-2022-0579"}],"prev":{"headline":"Capture-replay in Gitea","id":"CVE-2021-45327"},"products":["n/a"],"published":"2022-02-08","related":[{"cvss_score":9.8,"headline":"Gitea Code Injection","id":"CVE-2026-60004","kev_date_added":"2026-08-25","published":"2026-08-26"},{"cvss_score":9.8,"headline":"Gitea WebAuthn bypass during OAuth and OIDC sign-in","id":"CVE-2026-73278","kev_date_added":null,"published":"2026-10-06"},{"cvss_score":9.8,"headline":"Gitea fork workflow approval bypass through maintainer-triggered events","id":"CVE-2026-94205","kev_date_added":null,"published":"2026-10-06"},{"cvss_score":9.8,"headline":"Gitea vulnerable to Argument Injection","id":"CVE-2022-42968","kev_date_added":null,"published":"2022-10-16"},{"cvss_score":9.8,"headline":"Improper Privilege Management in Gitea","id":"CVE-2021-45330","kev_date_added":null,"published":"2022-02-09"},{"cvss_score":9.8,"headline":"Reuse of one time passwords allowed in Gitea","id":"CVE-2021-45331","kev_date_added":null,"published":"2022-02-09"},{"cvss_score":9.8,"headline":"Capture-replay in Gitea","id":"CVE-2021-45327","kev_date_added":null,"published":"2022-02-08"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can redirect users to untrusted sites via internal URLs in Gitea, potentially facilitating phishing attacks.","url":"https://insights.sbomify.com/CVE-2021-45328/"}
