An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-24853 in the wild and no public exploit code.\n\nAffected product: Unknown QR Redirector. 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-2021-24853/ (Markdown: https://insights.sbomify.com/CVE-2021-24853/index.md)","id":"CVE-2021-24853","markdown":"https://insights.sbomify.com/CVE-2021-24853/index.md","name":"CVE-2021-24853","record":{"aliases":["GHSA-gg89-hw93-j4hc"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Authenticated subscribers can modify arbitrary QR redirect response statuses due to missing capability and CSRF checks in the QR Redirector plugin.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"qr_redirector","vendor":"qr_redirector_project"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"The QR Redirector WordPress plugin before 1.6 does not have capability and CSRF checks when saving bulk QR Redirector settings via the qr_save_bulk AJAX action, which could allow any authenticated user, such as subscriber to change the redirect response status code of arbitrary QR Redirects","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"QR Redirector \u003c 1.6 - Subscriber+ Arbitrary QR Redirect Response Status Update","id":"CVE-2021-24853","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"QR Redirector \u003c 1.6.1 - Contributor+ Stored Cross-Site Scripting","id":"CVE-2021-24854"},"packages":[],"prev":{"headline":"MouseWheel Smooth Scroll \u003c 5.7 - Plugin's Setting Update via CSRF","id":"CVE-2021-24852"},"products":["QR Redirector"],"published":"2021-11-17","related":[{"cvss_score":5.4,"headline":"QR Redirector \u003c 1.6.1 - Contributor+ Stored Cross-Site Scripting","id":"CVE-2021-24854","kev_date_added":null,"published":"2021-11-17"}],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Unknown"]},"summary":"Authenticated subscribers can modify arbitrary QR redirect response statuses due to missing capability and CSRF checks in the QR Redirector plugin.","url":"https://insights.sbomify.com/CVE-2021-24853/"}
