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-2022-24880 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- flask-session-captcha (PyPI): affected all versions; fixed in 1.2.1\n- flask-session-captcha (PyPI): affected all versions; fixed in 1.2.1\n- flask-session-captcha (PyPI): affected all versions; fixed in 1.2.1\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-2022-24880/ (Markdown: https://insights.sbomify.com/CVE-2022-24880/index.md)","id":"CVE-2022-24880","markdown":"https://insights.sbomify.com/CVE-2022-24880/index.md","name":"CVE-2022-24880","record":{"aliases":["GHSA-7r87-cj48-wj45","PYSEC-2022-193"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Flask captcha library","requires_auth":"none","summary":"Attackers can bypass captcha validation in flask-session-captcha by submitting empty forms, allowing automated abuse of protected endpoints.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"flask-session-captcha","vendor":"flask-session-captcha_project"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"},{"id":"CWE-394","name":"Unexpected Status Code or Return Value"},{"id":"CWE-253","name":"Incorrect Check of Function Return Value"}],"description":"flask-session-captcha is a package which allows users to extend Flask by adding an image based captcha stored in a server side session. In versions prior to 1.2.1, he `captcha.validate()` function would return `None` if passed no value (e.g. by submitting an having an empty form). If implementing users were checking the return value to be **False**, the captcha verification check could be bypassed. Version 1.2.1 fixes the issue. Users can workaround the issue by not explicitly checking that the value is False. Checking the return value less explicitly should still work.","ecosystems":["PyPI"],"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":"Potential Captcha Validate Bypass in flask-session-captcha","id":"CVE-2022-24880","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"security_feature_bypass","year":"2022"},"n_packages":3,"n_references":4,"next":{"headline":"Command Injection in Ballcat Codegen","id":"CVE-2022-24881"},"packages":[{"ecosystem":"PyPI","fixed":["1.2.1"],"introduced":["0"],"last_affected":[],"package":"flask-session-captcha","purl":null,"source":"GHSA-7r87-cj48-wj45"},{"ecosystem":"PyPI","fixed":["1.2.1"],"introduced":["0"],"last_affected":[],"package":"flask-session-captcha","purl":"pkg:pypi/flask-session-captcha","source":"GHSA-7r87-cj48-wj45"},{"ecosystem":"PyPI","fixed":["1.2.1"],"introduced":["0"],"last_affected":[],"package":"flask-session-captcha","purl":"pkg:pypi/flask-session-captcha","source":"PYSEC-2022-193"}],"prev":{"headline":"Malfunction of Cross-Site Request Forgery token validation","id":"CVE-2022-24879"},"products":["flask-session-captcha"],"published":"2022-04-25","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":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"2025-04-23","vendors":["Tethik"]},"summary":"Attackers can bypass captcha validation in flask-session-captcha by submitting empty forms, allowing automated abuse of protected endpoints.","url":"https://insights.sbomify.com/CVE-2022-24880/"}
