An attacker needs administrator access to exploit it, 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-2026-9577 exists.\n\nAffected product: Unknown Post Status Notifier Lite. 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-2026-9577/ (Markdown: https://insights.sbomify.com/CVE-2026-9577/index.md)","id":"CVE-2026-9577","markdown":"https://insights.sbomify.com/CVE-2026-9577/index.md","name":"CVE-2026-9577","record":{"aliases":["GHSA-x9fx-2h43-2prm"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"high_privilege","summary":"Attackers can execute arbitrary scripts in an administrator's session via a crafted URL, potentially leading to account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/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 Post Status Notifier Lite WordPress plugin before 1.13.0 does not properly escape the `mod` URL parameter before reflecting it into the admin settings page (`admin.php?page=post-status-notifier-lite`), leading to a Reflected Cross-Site Scripting vulnerability that fires in the administrator's session when they are tricked into following a crafted URL.","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":"Post Status Notifier Lite \u003c 1.13.0 - Reflected XSS via mod Parameter","id":"CVE-2026-9577","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"JeecgBoot SysUser userEdit user.getUsername access control","id":"CVE-2026-9579"},"packages":[],"prev":{"headline":"Fluent Booking \u003c 2.1.2 - Calendar Manager+ Sensitive Information Disclosure via Attendee Export","id":"CVE-2026-9576"},"products":["Post Status Notifier Lite"],"published":"2026-07-23","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-23","vendors":["Unknown"]},"summary":"Attackers can execute arbitrary scripts in an administrator's session via a crafted URL, potentially leading to account takeover.","url":"https://insights.sbomify.com/CVE-2026-9577/"}
