An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-24488 exists.\n\nAffected product: Unknown Post Grid. 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-2021-24488/ (Markdown: https://insights.sbomify.com/CVE-2021-24488/index.md)","id":"CVE-2021-24488","markdown":"https://insights.sbomify.com/CVE-2021-24488/index.md","name":"CVE-2021-24488","record":{"aliases":["GHSA-grvg-w4gv-9v46"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Reflected XSS in Post Grid plugin allows attackers to execute arbitrary scripts via unsanitized slider import search and tab parameters.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"post_grid","vendor":"pickplugins"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The slider import search feature and tab parameter of the Post Grid WordPress plugin before 2.1.8 settings are not properly sanitised before being output back in the pages, leading to Reflected Cross-Site Scripting issues","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2022-02-02","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":"2022-02-02","kind":"exploitdb","ref":"50705","stars":null,"title":"WordPress Plugin Post Grid 2.1.1 - Cross Site Scripting (XSS)"},{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-24488.yaml","stars":null,"title":"WordPress Post Grid \u003c2.1.8 - Cross-Site Scripting"}],"tier":"weaponised"},"has_fix":null,"headline":"Post Grid \u003c 2.1.8 - Reflected Cross-Site Scripting (XSS)","id":"CVE-2021-24488","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Request a Quote \u003c 2.3.9 - Admin+ Stored Cross-Site Scripting","id":"CVE-2021-24489"},"packages":[],"prev":{"headline":"St Daily Tip \u003c= 4.7 - CSRF to Stored Cross-Site Scripting","id":"CVE-2021-24487"},"products":["Post Grid"],"published":"2021-08-02","related":[{"cvss_score":8.8,"headline":"Post Grid \u003c= 2.1.12 - Contributor+ SQL Injection","id":"CVE-2021-4450","kev_date_added":null,"published":"2024-10-16"},{"cvss_score":8.8,"headline":"Post Grid and Gutenberg Blocks 2.2.87 - 2.2.90 - Authenticated (Subscriber+) Privilege Escalation","id":"CVE-2024-8253","kev_date_added":null,"published":"2024-09-11"},{"cvss_score":7.5,"headline":"Path traversal in Post Grid, Slider \u0026 Carousel Ultimate – with Shortcode, Gutenberg Block \u0026 Elementor Widget","id":"CVE-2024-13408","kev_date_added":null,"published":"2025-01-24"},{"cvss_score":7.5,"headline":"Cross-site scripting in n/a","id":"CVE-2020-35936","kev_date_added":null,"published":"2021-01-01"},{"cvss_score":7.5,"headline":"Cross-site scripting in n/a","id":"CVE-2020-35937","kev_date_added":null,"published":"2021-01-01"},{"cvss_score":7.5,"headline":"Deserialization in n/a","id":"CVE-2020-35938","kev_date_added":null,"published":"2021-01-01"},{"cvss_score":7.5,"headline":"Deserialization in n/a","id":"CVE-2020-35939","kev_date_added":null,"published":"2021-01-01"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Unknown"]},"summary":"Reflected XSS in Post Grid plugin allows attackers to execute arbitrary scripts via unsanitized slider import search and tab parameters.","url":"https://insights.sbomify.com/CVE-2021-24488/"}
