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-2026-87764 in the wild and no public exploit code.\n\nAffected product: Unknown BuddyPress Instant Chat. 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-2026-87764/ (Markdown: https://insights.sbomify.com/CVE-2026-87764/index.md)","id":"CVE-2026-87764","markdown":"https://insights.sbomify.com/CVE-2026-87764/index.md","name":"CVE-2026-87764","record":{"aliases":["GHSA-q3fq-h679-wfvh"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can inject malicious scripts into chat messages, leading to code execution in victim sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The BuddyPress Instant Chat WordPress plugin through 1.6 does not check that the sender of a chat message belongs to the conversation it is being added to, nor does it escape message content before outputting it back, allowing unauthenticated users to store arbitrary web scripts that will execute in the session of any member who later views that conversation.","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":"BuddyPress Instant Chat \u003c= 1.6 - Unauthenticated Stored XSS via Chat Message","id":"CVE-2026-87764","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Improper Input Validation in Kernel APsys DVFS","id":"CVE-2026-87765"},"packages":[],"prev":{"headline":"Adwised Web Push Notification \u003c= 2.5.7 - Unauthenticated Stored XSS via Secret Key Type Juggling","id":"CVE-2026-87762"},"products":["BuddyPress Instant Chat"],"published":"2026-10-11","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":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-11","vendors":["Unknown"]},"summary":"Unauthenticated attackers can inject malicious scripts into chat messages, leading to code execution in victim sessions.","url":"https://insights.sbomify.com/CVE-2026-87764/"}
