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-2021-24881 exists.\n\nAffected product: Unknown Passster. 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-2021-24881/ (Markdown: https://insights.sbomify.com/CVE-2021-24881/index.md)","id":"CVE-2021-24881","markdown":"https://insights.sbomify.com/CVE-2021-24881/index.md","name":"CVE-2021-24881","record":{"aliases":["GHSA-c58r-vwf8-vx95"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can bypass password protection to access arbitrary private posts in the Passster WordPress plugin.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"passter","vendor":"passster_project"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[],"description":"The Passster WordPress plugin before 3.5.5.9 does not properly check for password, as well as that the post to be viewed is public, allowing unauthenticated users to bypass the protection offered by the plugin, and access arbitrary posts (such as private) content, by sending a specifically crafted request.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Passster \u003c 3.5.5.9 - Protection Bypass \u0026 Arbitrary Post Access","id":"CVE-2021-24881","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Slideshow Gallery \u003c 1.7.4 - Admin+ Stored Cross-Site Scripting","id":"CVE-2021-24882"},"packages":[],"prev":{"headline":"SupportCandy \u003c 2.2.7 - Contributor+ Stored Cross-Site Scripting","id":"CVE-2021-24880"},"products":["Passster"],"published":"2023-01-23","related":[{"cvss_score":5.4,"headline":"Passster \u003c 3.5.5.8 - Contributor+ Stored Cross-Site Scripting","id":"CVE-2021-24837","kev_date_added":null,"published":"2023-01-23"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-02","vendors":["Unknown"]},"summary":"Unauthenticated attackers can bypass password protection to access arbitrary private posts in the Passster WordPress plugin.","url":"https://insights.sbomify.com/CVE-2021-24881/"}
