An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-36567 and fix it if it is affected.\n\nWhat it is: CVE-2020-36567 is a high-severity vulnerability in github.com/gin-gonic/gin, published on 27 Dec 2022. 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-2020-36567 exists.\n\nAffected packages and fixed versions:\n- github.com/gin-gonic/gin (Go): affected all versions; fixed in 1.6.0\n- github.com/gin-gonic/gin (Go): affected all versions; fixed in 1.6.0\n- github.com/gin-gonic/gin (Go): affected all versions; fixed in 1.6.0\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-2020-36567/ (Markdown: https://insights.sbomify.com/CVE-2020-36567/index.md)","id":"CVE-2020-36567","markdown":"https://insights.sbomify.com/CVE-2020-36567/index.md","name":"CVE-2020-36567","record":{"aliases":["DEBIAN-CVE-2020-36567","GHSA-6vm3-jj99-7229","GO-2020-0001","UBUNTU-CVE-2020-36567"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Go web framework","requires_auth":"none","summary":"Remote attackers can inject arbitrary log lines via unsanitized input in the default logger of the Gin web framework.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Go","cpe":[{"product":"gin","vendor":"gin-gonic"}],"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:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"Unsanitized input in the default logger in github.com/gin-gonic/gin before v1.6.0 allows remote attackers to inject arbitrary log lines.","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":"Arbitrary log line injection in github.com/gin-gonic/gin","id":"CVE-2020-36567","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"other","year":"2020"},"n_packages":3,"n_references":3,"next":{"headline":"Resource exhaustion in github.com/revel/revel","id":"CVE-2020-36568"},"packages":[{"ecosystem":"Go","fixed":["1.6.0"],"introduced":["0"],"last_affected":[],"package":"github.com/gin-gonic/gin","purl":null,"source":"GHSA-6vm3-jj99-7229"},{"ecosystem":"Go","fixed":["1.6.0"],"introduced":["0"],"last_affected":[],"package":"github.com/gin-gonic/gin","purl":"pkg:golang/github.com/gin-gonic/gin","source":"GHSA-6vm3-jj99-7229"},{"ecosystem":"Go","fixed":["1.6.0"],"introduced":["0"],"last_affected":[],"package":"github.com/gin-gonic/gin","purl":"pkg:golang/github.com/gin-gonic/gin","source":"GO-2020-0001"}],"prev":{"headline":"Path traversal in github.com/whyrusleeping/tar-utils","id":"CVE-2020-36566"},"products":["github.com/gin-gonic/gin"],"published":"2022-12-27","related":[{"cvss_score":7.1,"headline":"HTTP Response Splitting","id":"CVE-2020-28483","kev_date_added":null,"published":"2021-01-20"},{"cvss_score":5.6,"headline":"Improper input validation in github.com/gin-gonic/gin","id":"CVE-2023-26125","kev_date_added":null,"published":"2023-05-04"},{"cvss_score":4.3,"headline":"Improper handling of filenames in Content-Disposition HTTP header in github.com/gin-gonic/gin","id":"CVE-2023-29401","kev_date_added":null,"published":"2023-06-08"}],"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":"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)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-11","vendors":["github.com/gin-gonic/gin"]},"summary":"Remote attackers can inject arbitrary log lines via unsanitized input in the default logger of the Gin web framework.","url":"https://insights.sbomify.com/CVE-2020-36567/"}
