Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-34370 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-2026-34370/ (Markdown: https://insights.sbomify.com/CVE-2026-34370/index.md)","id":"CVE-2026-34370","markdown":"https://insights.sbomify.com/CVE-2026-34370/index.md","name":"CVE-2026-34370","record":{"aliases":["GHSA-fm35-2hvw-564q"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Chamilo LMS","requires_auth":"low_privilege","summary":"Authenticated students can view other users' private course notes by manipulating the notebook ID, exposing sensitive data.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"chamilo_lms","vendor":"chamilo"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"},{"id":"CWE-285","name":"Improper Authorization"}],"description":"Chamilo LMS is an open-source learning management system. In versions prior to 2.0.0-RC.3, the notebook module contains an Insecure Direct Object Reference (IDOR) vulnerability that allows any authenticated student to read the private course notes of any other user on the platform by manipulating the notebook_id parameter in the editnote action. The application fetches the note content using only the supplied integer ID without verifying that the requesting user owns the note, and the full title and HTML body are rendered in the edit form and returned to the attacker's browser. While ownership checks exist in the write paths (updateNote() and delete_note()), they are entirely absent from the read path (get_note_information()). This issue has been fixed in version 2.0.0-RC.3.","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 LMS: IDOR in the Notebook Module allows an attacker to view other users' private notes","id":"CVE-2026-34370","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"chamilo:chamilo_lms","products":["chamilo:chamilo_lms"],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"LibreChat Affected by Arbitrary File Write via `execute_code` Artifact Filename Traversal","id":"CVE-2026-34371"},"packages":[],"prev":{"headline":"AVideo has Video Password Protection Bypass via API Endpoints Returning Full Playback Sources Without Password Verification","id":"CVE-2026-34369"},"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)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-15","vendors":["chamilo"]},"summary":"Authenticated students can view other users' private course notes by manipulating the notebook ID, exposing sensitive data.","url":"https://insights.sbomify.com/CVE-2026-34370/"}
