Aliases: CVE-2026-26047 GHSA-cg8j-5cr2-568q |
Moodle TeX formula editor is vulnerable to DoS through lack of execution time limits A Denial of Service vulnerability was identified in Moodle’s TeX formula editor. When rendering TeX content using mimetex, insufficient execution time limits could allow specially crafted formulas to consume excessive server resources. An authenticated user could abuse this behavior to degrade performance or cause service interruption. |

Moodle has a Remote Code Execution risk via file restore A flaw was identified in Moodle’s backup restore functionality where specially crafted backup files were not properly validated during processing. If a malicious backup file is restored, it could lead to unintended execution of server-side code. Since restore capabilities are typically available to privileged users, exploitation requires authenticated access. Successful exploitation could result in full compromise of the Moodle server. |

| VCID-4nvk-z7mr-aqfx | Moodle Open Redirect vulnerability A flaw was found in Moodle. An Open Redirect vulnerability in the OAuth login flow allows a remote attacker to redirect users to attacker-controlled pages after they have successfully authenticated. This occurs due to insufficient validation of redirect parameters, which could lead to phishing attacks or information disclosure. |
CVE-2025-67852
GHSA-qv78-6gpp-hm68 |
| VCID-56mc-ejh5-d7gh | Moodle has an authorization logic flaw A flaw was found in Moodle. An authorization logic flaw, specifically due to incomplete role checks during the badge awarding process, allowed badges to be granted without proper verification. This could enable unauthorized users to obtain badges they are not entitled to, potentially leading to privilege escalation or unauthorized access to certain features. |
CVE-2025-67856
GHSA-hcm6-q6pc-xfhm |
| VCID-6tjn-fck1-rub7 | Moodle Inserts Sensitive Information Into Sent Data A flaw was found in moodle. During anonymous assignment submissions, user identifiers were inadvertently exposed in URLs. This data exposure allows unauthorized viewers to see internal user IDs, compromising the intended anonymity and potentially leading to information disclosure. |
CVE-2025-67857
GHSA-8jrv-wx83-w3xj |
| VCID-92r9-v939-yud7 | Moodle formula injection vulnerability A flaw was found in Moodle. This formula injection vulnerability occurs when data fields are exported without proper escaping. A remote attacker could exploit this by providing malicious data that, when exported and opened in a spreadsheet, allows arbitrary formulas to execute. This can lead to compromised data integrity and unintended operations within the spreadsheet. |
CVE-2025-67851
GHSA-qfh6-h7j6-fvjv |
| VCID-bxjs-u47s-4uds | Moodle vulnerable to Cross-site Scripting A flaw was found in Moodle. A remote attacker could exploit a reflected Cross-Site Scripting (XSS) vulnerability in the policy tool return URL. This vulnerability arises from insufficient sanitization of URL parameters, allowing attackers to inject malicious scripts through specially crafted links. Successful exploitation could lead to information disclosure or arbitrary client-side script execution within the user's browser. |
CVE-2025-67855
GHSA-vwhw-vp9v-q9c9 |
| VCID-khsn-h84k-2kad | Moodle vulnerable to Cross-site Scripting A flaw was found in Moodle. This vulnerability, known as Cross-site Scripting (XSS), occurs due to insufficient checks on user-provided data in the formula editor's arithmetic expression fields. A remote attacker could inject malicious code into these fields. When other users view these expressions, the malicious code would execute in their web browsers, potentially compromising their data or leading to unauthorized actions. |
CVE-2025-67850
GHSA-6mmv-f6c6-v6q8 |
| VCID-pssp-b34q-vqcw | Moodle Affected by Improper Restriction of Excessive Authentication Attempts A flaw was found in Moodle. A remote attacker could exploit a lack of proper rate limiting in the confirmation email service. This vulnerability allows attackers to more easily enumerate or guess user credentials, facilitating brute-force attacks against user accounts. |
CVE-2025-67853
GHSA-5cx4-w4fh-fr57 |
| VCID-w1d6-9ytv-rqbj | Moodle authentication bypass vulnerability A flaw was found in Moodle. This authentication bypass vulnerability allows suspended users to authenticate through the Learning Tools Interoperability (LTI) Provider. The issue arises from the LTI authentication handlers failing to enforce the user's suspension status, enabling unauthorized access to the system. This can lead to information disclosure or other unauthorized actions by users who should be restricted. |
CVE-2025-67848
GHSA-j5jv-w5cw-j9ff |
| VCID-xabq-b33t-4yau | Moodle Cross-site Scripting (XSS) vulnerability A flaw was found in Moodle. This Cross-site Scripting (XSS) vulnerability, caused by improper sanitization of AI prompt responses, allows attackers to inject malicious HTML or script into web pages. When other users view these compromised pages, their sessions could be stolen, or the user interface could be manipulated. |
CVE-2025-67849
GHSA-mhf6-pp52-8wqj |
| VCID-z28b-byu6-97f1 | Moodle affected by a code injection vulnerability A flaw was found in Moodle. An attacker with access to the restore interface could trigger server-side execution of arbitrary code. This is due to insufficient validation of restore input, which leads to unintended interpretation by core restore routines. Successful exploitation could result in a full compromise of the Moodle application. |
