Moodle's mobile and web service authentication endpoints did not sufficiently restrict repeated password attempts, making them susceptible to brute-force attacks.

An issue in Moodle's timed assignment feature allowed students to bypass the time restriction, potentially giving them more time than allowed to complete an assessment.

A flaw was found in the course overview output function where user access permissions were not fully enforced. This could allow unauthorized users to view information about courses they should not have access to, potentially exposing limited course details.

Moodle failed to verify enrolment status correctly when sending quiz notifications. As a result, suspended or inactive users might receive quiz-related messages, leaking limited course information.

Slack Nebula before 1.9.7 mishandles CIDR in some configurations and thus accepts arbitrary source IP addresses within the Nebula network.

Safe functions accept a single `&T` or `&mut T` but multiply by `n` to create slices extending beyond allocated memory when `n > 1`. These functions use `from_raw_parts` to create slices larger than the underlying allocation, violating memory safety. The binary_vec_io repository is archived and unmaintained.

Missing Authorization in Collection Provider component in the Liferay Portal 7.4.0 through 7.4.3.132, and Liferay DXP 2025.Q2.0 through 2025.Q2.9, 2025.Q1.0 through 2025.Q1.16, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.0 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.19 allows instance users to read and select unauthorized Blueprints through the Collection Providers across instances.

A reflected cross-site scripting (XSS) vulnerability, resulting from a regression, has been identified in Liferay Portal 7.4.0 through 7.4.3.132, and Liferay DXP 2025.Q2.0 through 2025.Q2.9, 2025.Q1.0 through 2025.Q1.16, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.1 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.19 allows a remote, authenticated attacker to inject and execute JavaScript code via the _com_liferay_dynamic_data_mapping_web_portlet_DDMPortlet_definition parameter. The malicious payload is executed within the victim's browser when they access a URL that includes the crafted parameter.

### Impact OpenBao's audit log did not appropriately redact fields when relevant subsystems sent `[]byte` response parameters rather than `string`s. This includes, but is not limited to: - `sys/raw` with use of `encoding=base64`, all data would be emitted unredacted to the audit log. - Transit, when performing a signing operation with a derived Ed25519 key, would emit public keys to the audit log. Third-party plugins may be affected. This issue has been present since HashiCorp Vault and continues to impact Vault as of v1.20.4. ### Patches OpenBao v2.4.2 will patch this issue. ### Workarounds If users do not use the above functionality, they are not impacted. To prohibit the use of `sys/raw` globally, ensure `raw_storage_endpoint=false` is set or missing from the server configuration.

### Impact EncryptionUtilityServiceImpl initialized an AES256TextEncryptor password (serverSecretKey) using RandomStringUtils with the default java.util.Random. java.util.Random is a non‑cryptographic PRNG and can be predicted from limited state/seed information (e.g., start time window), substantially reducing the effective search space of the generated key. An attacker who can obtain ciphertexts (e.g., exported or at‑rest strings protected by this service) and approximate the PRNG seed can feasibly reconstruct the serverSecretKey and decrypt affected data. ### Patches SAK-49866 is patched in Sakai 23.5, 25.0, and trunk. ### Credits - Reported by [Suraj Gangwar](https://www.linkedin.com/in/surajgangwar?trk=contact-info). - Patched by Sam Ottenhoff (Longsight).
