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-2020-37255 exists.\n\nAffected product: Wptimecapsule Time Capsule Plugin. 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-2020-37255/ (Markdown: https://insights.sbomify.com/CVE-2020-37255/index.md)","id":"CVE-2020-37255","markdown":"https://insights.sbomify.com/CVE-2020-37255/index.md","name":"CVE-2020-37255","record":{"aliases":["GHSA-4jwp-2g8r-6m99"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can gain administrative access to WordPress sites using the Time Capsule plugin by sending a crafted POST request.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"WordPress Time Capsule Plugin 1.21.16 contains an authentication bypass vulnerability that allows unauthenticated attackers to gain administrative access by sending a crafted POST request with the IWP_JSON_PREFIX header.
