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-2025-53838 exists.\n\nAffected product: Kovah LinkAce. 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-2025-53838/ (Markdown: https://insights.sbomify.com/CVE-2025-53838/index.md)","id":"CVE-2025-53838","markdown":"https://insights.sbomify.com/CVE-2025-53838/index.md","name":"CVE-2025-53838","record":{"aliases":["GHSA-vwmx-v9qf-q656"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"LinkAce link archive","requires_auth":"low_privilege","summary":"Attackers can inject malicious JavaScript into LinkAce links, executing arbitrary code in victims' browsers upon clicking, potentially leading to account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"linkace","vendor":"linkace"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"LinkAce is a self-hosted archive to collect website links. A stored cross-site scripting (XSS) vulnerability was discovered in versions prior to 2.1.9 that allows an attacker to inject arbitrary JavaScript, which is then executed in the context of a user's browser when the malicious link is clicked. This is a one-click XSS, meaning the victim only needs to click a crafted link — no further interaction is required. The application contains a stored XSS vulnerability due to insufficient filtering and escaping of user-supplied data inserted into link attributes. Malicious JavaScript code can be saved in the database along with the link and executed in the user’s browser when clicking the link, leading to arbitrary script execution within the context of the site. Version 2.1.9 fixes the issue.","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":"LinkAce has a Stored One Click XSS vulnerability","id":"CVE-2025-53838","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"DRACOON Branding Service vulnerable to Cross-site Scripting","id":"CVE-2025-53839"},"packages":[],"prev":{"headline":"org.xwiki.rendering:xwiki-rendering-xml has an Eval Injection issue","id":"CVE-2025-53837"},"products":["LinkAce"],"published":"2025-09-08","related":[{"cvss_score":8.7,"headline":"LinkAce: Stored XSS in Atom Feed via CDATA Escape in List Description","id":"CVE-2026-27458","kev_date_added":null,"published":"2026-02-21"},{"cvss_score":8.7,"headline":"LinkAce: Stored XSS Vulnerability in Link Title Field Through Social Media Sharing Feature","id":"CVE-2025-62722","kev_date_added":null,"published":"2025-11-04"},{"cvss_score":8.5,"headline":"LinkAce's SSRF protection can be bypassed via internal hostname resolution in LinkAce","id":"CVE-2026-33953","kev_date_added":null,"published":"2026-03-27"},{"cvss_score":7.7,"headline":"LinkAce affected by SSRF via link creation: NoPrivateIpRule not applied to LinkStoreRequest","id":"CVE-2026-30953","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":7.6,"headline":"File Upload Vulnerability Leading to XSS in LinkAce v1.15.5","id":"CVE-2024-56508","kev_date_added":null,"published":"2024-12-27"},{"cvss_score":7.3,"headline":"LinkAce Vulnerable to Stored XSS on the Audit Page","id":"CVE-2025-59424","kev_date_added":null,"published":"2025-09-18"}],"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":"total"},"state":"PUBLISHED","updated":"2025-09-08","vendors":["Kovah"]},"summary":"Attackers can inject malicious JavaScript into LinkAce links, executing arbitrary code in victims' browsers upon clicking, potentially leading to account takeover.","url":"https://insights.sbomify.com/CVE-2025-53838/"}
