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-2023-45141 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/gofiber/fiber/v2 (Go): affected all versions; fixed in 2.50.0\n- github.com/gofiber/fiber/v2 (Go): affected all versions; fixed in 2.50.0\n- github.com/gofiber/fiber/v2 (Go): affected all versions; fixed in 2.50.0\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-2023-45141/ (Markdown: https://insights.sbomify.com/CVE-2023-45141/index.md)","id":"CVE-2023-45141","markdown":"https://insights.sbomify.com/CVE-2023-45141/index.md","name":"CVE-2023-45141","record":{"aliases":["GHSA-mv73-f69x-444p","GO-2023-2116"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["account_takeover","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Go web framework","requires_auth":"none","summary":"Attackers can forge malicious requests on behalf of users due to improper CSRF token validation in the Fiber Go web framework.","user_interaction":"not_required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"fiber","vendor":"gofiber"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-565","name":"Reliance on Cookies without Validation and Integrity Checking"},{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Fiber is an express inspired web framework written in Go. A Cross-Site Request Forgery (CSRF) vulnerability has been identified in the application, which allows an attacker to obtain tokens and forge malicious requests on behalf of a user. This can lead to unauthorized actions being taken on the user's behalf, potentially compromising the security and integrity of the application. The vulnerability is caused by improper validation and enforcement of CSRF tokens within the application. This vulnerability has been addressed in version 2.50.0 and users are advised to upgrade. Users should take additional security measures like captchas or Two-Factor Authentication (2FA) and set Session cookies with SameSite=Lax or SameSite=Secure, and the Secure and HttpOnly attributes.","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":"CSRF Token Validation Vulnerability in fiber","id":"CVE-2023-45141","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"csrf","year":"2023"},"n_packages":3,"n_references":1,"next":{"headline":"OpenTelemetry-Go Contrib has DoS vulnerability in otelhttp due to unbound cardinality metrics","id":"CVE-2023-45142"},"packages":[{"ecosystem":"Go","fixed":["2.50.0"],"introduced":["0"],"last_affected":[],"package":"github.com/gofiber/fiber/v2","purl":null,"source":"GHSA-mv73-f69x-444p"},{"ecosystem":"Go","fixed":["2.50.0"],"introduced":["0"],"last_affected":[],"package":"github.com/gofiber/fiber/v2","purl":"pkg:golang/github.com/gofiber/fiber/v2","source":"GHSA-mv73-f69x-444p"},{"ecosystem":"Go","fixed":["2.50.0"],"introduced":["0"],"last_affected":[],"package":"github.com/gofiber/fiber/v2","purl":"pkg:golang/github.com/gofiber/fiber/v2","source":"GO-2023-2116"}],"prev":{"headline":"Group-based JIT MFA bypass on scp and sftp in The Bastion","id":"CVE-2023-45140"},"products":["fiber"],"published":"2023-10-16","related":[{"cvss_score":10,"headline":"Fiber Session Middleware Token Injection Vulnerability","id":"CVE-2024-38513","kev_date_added":null,"published":"2024-07-01"},{"cvss_score":10,"headline":"CSRF Token Reuse Vulnerability in fiber","id":"CVE-2023-45128","kev_date_added":null,"published":"2023-10-16"},{"cvss_score":9.4,"headline":"Fiber has Insecure CORS Configuration, Allowing Wildcard Origin with Credentials","id":"CVE-2024-25124","kev_date_added":null,"published":"2024-02-21"},{"cvss_score":9.2,"headline":"Fiber insecurely fallsback in utils.UUIDv4() / utils.UUID() — predictable / zero‑UUID on crypto/rand failure","id":"CVE-2025-66630","kev_date_added":null,"published":"2026-02-09"},{"cvss_score":8.7,"headline":"Fiber Susceptible to Crash via `BodyParser` Due to Unvalidated Large Slice Index in Decoder","id":"CVE-2025-54801","kev_date_added":null,"published":"2025-08-05"},{"cvss_score":7.7,"headline":"Fiber has an Arbitrary File Read in Static Middleware on Windows","id":"CVE-2026-25891","kev_date_added":null,"published":"2026-02-24"}],"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-16","vendors":["gofiber"]},"summary":"Attackers can forge malicious requests on behalf of users due to improper CSRF token validation in the Fiber Go web framework.","url":"https://insights.sbomify.com/CVE-2023-45141/"}
