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-2025-51859 exists.\n\nAffected product: n/a. 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-2025-51859/ (Markdown: https://insights.sbomify.com/CVE-2025-51859/index.md)","id":"CVE-2025-51859","markdown":"https://insights.sbomify.com/CVE-2025-51859/index.md","name":"CVE-2025-51859","record":{"aliases":["GHSA-cv56-r9m6-79rx"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Chaindesk AI agent","requires_auth":"none","summary":"Attackers can execute arbitrary scripts in users' browsers via malicious AI agent prompts, leading to session token theft and account hijacking.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Stored Cross-Site Scripting (XSS) vulnerability in Chaindesk thru 2025-05-26 in its agent chat component. An attacker can achieve arbitrary client-side script execution by crafting an AI agent whose system prompt instructs the underlying Large Language Model (LLM) to embed malicious script payloads (e.g., SVG-based XSS) into its chat responses. When a user interacts with such a malicious agent or accesses a direct link to a conversation containing an XSS payload, the script executes in the user's browser. Successful exploitation can lead to the theft of sensitive information, such as JWT session tokens, potentially resulting in account hijacking.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-07-19","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-07-19T09:03:43Z","kind":"github_poc","ref":"https://github.com/Secsys-FDU/CVE-2025-51859","stars":0,"title":null}],"tier":"weaponised"},"has_fix":null,"headline":"Cross-site scripting in n/a","id":"CVE-2025-51859","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2025-51860"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2025-51858"},"products":["n/a"],"published":"2025-07-22","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-07-22","vendors":["n/a"]},"summary":"Attackers can execute arbitrary scripts in users' browsers via malicious AI agent prompts, leading to session token theft and account hijacking.","url":"https://insights.sbomify.com/CVE-2025-51859/"}
