Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-26212 in the wild and no public exploit code.\n\nAffected product: Glpi-Project Glpi. 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-2020-26212/ (Markdown: https://insights.sbomify.com/CVE-2020-26212/index.md)","id":"CVE-2020-26212","markdown":"https://insights.sbomify.com/CVE-2020-26212/index.md","name":"CVE-2020-26212","record":{"aliases":["GHSA-qmw3-87hr-5wgx"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"IT asset management","requires_auth":"low_privilege","summary":"Any authenticated user can read other users' personal and group calendars via CalDAV, exposing sensitive scheduling data.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"glpi","vendor":"glpi-project"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"GLPI stands for Gestionnaire Libre de Parc Informatique and it is a Free Asset and IT Management Software package, that provides ITIL Service Desk features, licenses tracking and software auditing. In GLPI before version 9.5.3, any authenticated user has read-only permissions to the planning of every other user, even admin ones. Steps to reproduce the behavior: 1. Create a new planning with 'eduardo.mozart' user (from 'IT' group that belongs to 'Super-admin') into it's personal planning at 'Assistance' \u003e 'Planning'. 2. Copy the CalDAV url and use a CalDAV client (e.g. Thunderbird) to sync the planning with the provided URL. 3. Inform the username and password from any valid user (e.g. 'camila' from 'Proativa' group). 4. 'Camila' has read-only access to 'eduardo.mozart' personal planning. The same behavior happens to any group. E.g. 'Camila' has access to 'IT' group planning, even if she doesn't belong to this group and has a 'Self-service' profile permission). This issue is fixed in version 9.5.3. As a workaround, one can remove the `caldav.php` file to block access to CalDAV server.","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":"Any GLPI CalDAV calendars is read-only for every authenticated user","id":"CVE-2020-26212","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"glpi-project:glpi","products":["glpi-project:glpi"],"type":"missing_authorization","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of Service in teler","id":"CVE-2020-26213"},"packages":[],"prev":{"headline":"Cross-Site Scripting in BookStack","id":"CVE-2020-26211"},"products":["glpi"],"published":"2020-11-25","related":[{"cvss_score":9.8,"headline":"Teclib GLPI Remote Code Execution","id":"CVE-2022-35914","kev_date_added":"2023-03-07","published":"2022-09-19"},{"cvss_score":10,"headline":"GLPI vulnerable to unallowed PHP script execution","id":"CVE-2023-42802","kev_date_added":null,"published":"2023-11-02"},{"cvss_score":10,"headline":"GLPI vulnerable to SQL injection and Stored XSS via inventory agent request","id":"CVE-2023-28849","kev_date_added":null,"published":"2023-04-05"},{"cvss_score":10,"headline":"SQL injection in GLPI","id":"CVE-2022-35947","kev_date_added":null,"published":"2022-09-14"},{"cvss_score":9.8,"headline":"SQL injection with _actor parameter in GLPI","id":"CVE-2022-31056","kev_date_added":null,"published":"2022-06-28"},{"cvss_score":9.8,"headline":"SQL injection on login page in GLPI","id":"CVE-2022-31061","kev_date_added":null,"published":"2022-06-28"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2021-44617","kev_date_added":null,"published":"2022-03-28"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["glpi-project"]},"summary":"Any authenticated user can read other users' personal and group calendars via CalDAV, exposing sensitive scheduling data.","url":"https://insights.sbomify.com/CVE-2020-26212/"}
