Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-35196 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-2026-35196/ (Markdown: https://insights.sbomify.com/CVE-2026-35196/index.md)","id":"CVE-2026-35196","markdown":"https://insights.sbomify.com/CVE-2026-35196/index.md","name":"CVE-2026-35196","record":{"aliases":["GHSA-crc6-r6c7-44q3"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","data_read","data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Chamilo LMS","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary OS commands via session poisoning in Chamilo LMS, leading to full server compromise.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"chamilo_lms","vendor":"chamilo"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Chamilo LMS is an open-source learning management system. In versions prior to 2.0.0-RC.3, an OS Command Injection vulnerability exists in the main/inc/ajax/gradebook.ajax.php endpoint within the export_all_certificates action, where the course code retrieved from the session variable $_SESSION['_cid'] via api_get_course_id() is concatenated directly into a shell_exec() command string without sanitization or escaping using escapeshellarg(). If an attacker can manipulate or poison their session data to inject shell metacharacters into the _cid variable, they can achieve arbitrary command execution on the underlying server. Successful exploitation grants full access to read system files and credentials, alters the application and database, or disrupts server availability. This issue has been fixed in version 2.0.0-RC.3.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-04-02","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-04-02T02:04:10Z","kind":"github_poc","ref":"https://github.com/kx00007/CVE-2026-35196","stars":0,"title":"Second CVE still Remote Code Execution "}],"tier":"poc_unverified"},"has_fix":false,"headline":"Chamilo LMS has OS Command Injection via export_all_certificates action","id":"CVE-2026-35196","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"chamilo:chamilo_lms","products":["chamilo:chamilo_lms"],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Code injection in dye template expressions","id":"CVE-2026-35197"},"packages":[],"prev":{"headline":"Wasmtime has an out-of-bounds write or crash when transcoding component model strings","id":"CVE-2026-35195"},"products":["chamilo-lms"],"published":"2026-04-14","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-15","vendors":["chamilo"]},"summary":"Attackers can execute arbitrary OS commands via session poisoning in Chamilo LMS, leading to full server compromise.","url":"https://insights.sbomify.com/CVE-2026-35196/"}
