Any signed-in user can exploit it over the network, 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-2026-10850 exists.\n\nAffected product: Plane. 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-2026-10850/ (Markdown: https://insights.sbomify.com/CVE-2026-10850/index.md)","id":"CVE-2026-10850","markdown":"https://insights.sbomify.com/CVE-2026-10850/index.md","name":"CVE-2026-10850","record":{"aliases":["GHSA-4fp8-7gvj-j2xg"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Plane project management","requires_auth":"low_privilege","summary":"A low-privileged user can inject malicious scripts into intake work item descriptions, potentially compromising other users' sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Fluid Attacks","cpe":[{"product":"plane","vendor":"plane"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:N/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Plane CE 1.3.1 allows a low-privileged project member to submit arbitrary HTML/JS in the description_html field when creating an intake work item through the API v1 intake endpoint.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Plane 1.3.1 - Stored XSS in intake issue description_html","id":"CVE-2026-10850","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Websphere Application Server is Affected By a Denial of Service","id":"CVE-2026-10852"},"packages":[],"prev":{"headline":"Heap out-of-bounds write in Zephyr hawkBit OTA client when terminating server response body","id":"CVE-2026-10849"},"products":["Plane"],"published":"2026-06-17","related":[{"cvss_score":9.3,"headline":"Plane allows server side request forgery via /_next/image endpoint","id":"CVE-2024-47830","kev_date_added":null,"published":"2024-10-11"},{"cvss_score":8.5,"headline":"Plane: SSRF via Incomplete IP Validation in Webhook URL Serializer","id":"CVE-2026-30242","kev_date_added":null,"published":"2026-03-06"},{"cvss_score":8.3,"headline":"Missing authorization in plane","id":"CVE-2026-46558","kev_date_added":null,"published":"2026-06-10"},{"cvss_score":7.7,"headline":"Plane has a Server-Side Request Forgery (SSRF) in Favicon Fetching","id":"CVE-2026-39843","kev_date_added":null,"published":"2026-04-09"},{"cvss_score":7.7,"headline":"Plane Vulnerable to Full Read SSRF via Favicon Fetching in \"Add Link\" Feature","id":"CVE-2026-27706","kev_date_added":null,"published":"2026-02-25"},{"cvss_score":7.5,"headline":"Plane: Unauthenticated Workspace Member Information Disclosure","id":"CVE-2026-30244","kev_date_added":null,"published":"2026-03-06"},{"cvss_score":7.1,"headline":"Plane v0.7.1 - Unauthorized access to files","id":"CVE-2023-2268","kev_date_added":null,"published":"2023-07-15"}],"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-17","vendors":["Plane"]},"summary":"A low-privileged user can inject malicious scripts into intake work item descriptions, potentially compromising other users' sessions.","url":"https://insights.sbomify.com/CVE-2026-10850/"}
