{"id":"CVE-2026-33698","summary":"Chamilo LMS affected by unauthenticated RCE in main/install folder","details":"Chamilo LMS is a learning management system. Prior to 1.11.38, a chained attack can enable otherwise-blocked PHP code from the main/install/ directory and allow an unauthenticated attacker to modify existing files or create new files where allowed by system permissions. This only affects portals with the main/install/ directory still present and read-accessible. This vulnerability is fixed in 1.11.38.","aliases":["GHSA-557g-2w66-gpmf"],"modified":"2026-07-15T01:49:05.921432012Z","published":"2026-04-10T18:14:17.424Z","database_specific":{"cwe_ids":["CWE-552"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33698.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33698.json"},{"type":"ADVISORY","url":"https://github.com/chamilo/chamilo-lms/security/advisories/GHSA-557g-2w66-gpmf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33698"},{"type":"FIX","url":"https://github.com/chamilo/chamilo-lms/commit/d3355d7873c7e5b907c5fa84cbd5d9b62ed33e51"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/chamilo/chamilo-lms","events":[{"introduced":"0"},{"fixed":"abb5547a46a96339dfe6079e9b7ecd329bca181a"},{"fixed":"d3355d7873c7e5b907c5fa84cbd5d9b62ed33e51"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:chamilo:chamilo_lms:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.11.38"}]}}],"versions":["v1.11.36","v1.11.32","v1.11.30","v1.11.30-rc.1","v1.11.28","v1.11.26","v1.11.26-rc.1","v1.11.24","v1.11.22","v1.11.22-beta.2","v1.11.22-beta.1","v1.11.20-beta.1","v1.11.20","v1.11.18","v1.11.14","v1.11.14-beta.1","v1.11.12","v1.11.10","v1.11.6","v1.11.6-alpha.1","v1.9.8","CHAMILO_1_9_6_STABLE","CHAMILO_1_9_6_RC_2","CHAMILO_1_9_6_RC_1","CHAMILO_1_9_4_STABLE","CHAMILO_1_9_4_RC_1","CHAMILO_1_9_4_ALPHA_1","CHAMILO_1_9_2_STABLE_QUARTER","CHAMILO_1_9_2_STABLE","CHAMILO_1_9_0_STABLE_3","CHAMILO_1_9_0_STABLE_2","CHAMILO_1_9_0_RC_1","CHAMILO_1_8_8_4_STABLE","CHAMILO_1_9_0_ALPHA_4","CHAMILO_1_9_0_ALPHA_2","CHAMILO_1_9_0_ALPHA_1","CHAMILO_1_9_0_PRE_ALPHA","CHAMILO_1_8_8.3_STABLE_4","CHAMILO_1_8_8_2_STABLE_2","CHAMILO_1_8_8_2_STABLE","CHAMILO_1_8_8_2_RC_1","CHAMILO_1_8_8_BETA_2","CHAMILO_1_8_8_BETA_1","CHAMILO_1_8_8_ALPHA","CHAMILO_1_8_7_STABLE_BIS","CHAMILO_1_8_7_STABLE","CHAMILO_1_8_7_RC2","CHAMILO_1_8_7_RC_1","CHAMILO_1_8_7_ALPHA_2","CHAMILO_1_8_7_ALPHA_1","v1.8.6.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33698.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
