Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-59543 in the wild and no public exploit code.\n\nAffected product: Chamilo Chamilo Lms. 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-2025-59543/ (Markdown: https://insights.sbomify.com/CVE-2025-59543/index.md)","id":"CVE-2025-59543","markdown":"https://insights.sbomify.com/CVE-2025-59543/index.md","name":"CVE-2025-59543","record":{"aliases":["GHSA-p32q-6gh3-3gcv"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Chamilo LMS","requires_auth":"low_privilege","summary":"Attackers can inject malicious scripts into course descriptions to steal session cookies and take over administrator accounts in Chamilo LMS.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"chamilo_lms","vendor":"chamilo"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Chamilo is a learning management system. Prior to version 1.11.34, there is a stored cross-site scripting (XSS) vulnerability. By injecting malicious JavaScript into the course description field, an attacker with a low-privileged account (e.g., trainer) can execute arbitrary JavaScript code in the context of any other user viewing the course information page, including administrators. This allows an attacker to exfiltrate sensitive session cookies or tokens, resulting in account takeover (ATO) of higher-privileged users. This issue has been patched in version 1.11.34.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Chamilo: Account Takeover via Stored XSS in Course Description","id":"CVE-2025-59543","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"chamilo:chamilo_lms","products":["chamilo:chamilo_lms"],"type":"xss","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Chamilo: Unauthorized access to update category of any user","id":"CVE-2025-59544"},"packages":[],"prev":{"headline":"Chamilo: Account Takeover via Stored XSS in Course Learning Paths","id":"CVE-2025-59542"},"products":["chamilo-lms"],"published":"2026-03-06","related":[{"cvss_score":9.8,"headline":"Chamilo: Evaluation of untrusted user input leads to Remote Code Execution","id":"CVE-2025-50187","kev_date_added":null,"published":"2026-03-02"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2023-34944","kev_date_added":null,"published":"2023-06-13"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2022-27423","kev_date_added":null,"published":"2022-04-15"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2021-35414","kev_date_added":null,"published":"2021-12-03"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2019-13082","kev_date_added":null,"published":"2019-06-30"},{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2018-1999019","kev_date_added":null,"published":"2018-07-23"},{"cvss_score":9.4,"headline":"Weak Password Recovery Mechanism for Forgotten Password in chamilo/chamilo-lms","id":"CVE-2026-33707","kev_date_added":null,"published":"2026-04-10"}],"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":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-09","vendors":["chamilo"]},"summary":"Attackers can inject malicious scripts into course descriptions to steal session cookies and take over administrator accounts in Chamilo LMS.","url":"https://insights.sbomify.com/CVE-2025-59543/"}
