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-2026-125439 in the wild and no public exploit code.\nExposure: An affected version is exposed as installed. No special setting or call is needed.\n\nAffected product: Kit (formerly ConvertKit). No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-125439/ (Markdown: https://insights.sbomify.com/CVE-2026-125439/index.md)","id":"CVE-2026-125439","markdown":"https://insights.sbomify.com/CVE-2026-125439/index.md","name":"CVE-2026-125439","record":{"aliases":[],"analysis":{"component_type":"cms_plugin","exploitable_when_present":false,"fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","requires_specific_call":false,"summary":"Attackers can exploit missing authorization checks in the Kit (formerly ConvertKit) WordPress plugin to perform restricted actions.","user_interaction":"not_required","vuln_class":"missing_authorization","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"Patchstack","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Missing Authorization vulnerability in Kit Kit (formerly ConvertKit) convertkit allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Kit (formerly ConvertKit): from n/a through 3.5.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-11-03","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-11-03T13:02:18Z","kind":"github_poc","ref":"https://github.com/kanokwut/CVE-2026-125439-poc","stars":0,"title":"PoC for CVE-2026-125439: Kit (formerly ConvertKit) Member Content paywall bypass via the REST API excerpt field.
