The Joint Cyber Defense Collaborative playbook seeks to establish a "a unified approach" on how to handle AI-related cybersecurity threats.

### Impact _What kind of vulnerability is it? Who is impacted?_ Remote code execution may be possible in web-accessible installations of Homarus in certain configurations. ### Patches _Has the problem been patched? What versions should users upgrade to?_ The issue has been patched in `islandora/crayfish:4.1.0` ### Workarounds _Is there a way for users to fix or remediate the vulnerability without upgrading?_ The exploit requires making a request against the Homarus's `/convert` endpoint; therefore, the ability to exploit is much reduced if the microservice is not directly accessible from the Internet, so: Prevent general access from the Internet from hitting Homarus. Configure auth in Crayfish to be more strongly required, such that requests with `Authorization` headers that do not validate are rejected before the problematic CLI interpolation occurs. ### References _Are there any links users can visit to find out more?_ - XBOW-024-071

It's an especially brazen form of malvertising, researchers say, striking at the heart of Google's business; the tech giant says it's aware of the issue and is working quickly to address the problem.

### Impact A critical vulnerability was discovered in the SAML SSO implementation of Sentry. It was reported to us via our private bug bounty program. The vulnerability allows an attacker to take over any user account by using a malicious SAML Identity Provider and another organization on the same Sentry instance. The victim email address must be known in order to exploit this vulnerability. ### Patches - [Sentry SaaS](https://sentry.io): The fix was deployed on Jan 14, 2025. - [Self-Hosted Sentry](https://github.com/getsentry/self-hosted): If only a single organization is allowed (`SENTRY_SINGLE_ORGANIZATION = True`), then no action is needed. Otherwise, users should upgrade to version 25.1.0 or higher. ### Workarounds No known workarounds. ### References - https://github.com/getsentry/sentry/pull/83407

Mattermost versions 10.2.x <= 10.2.0, 9.11.x <= 9.11.5, 10.0.x <= 10.0.3, 10.1.x <= 10.1.3 fail to properly validate post props which allows a malicious authenticated user to cause a crash via a malicious post.

Mattermost versions 10.2.x <= 10.2.0, 9.11.x <= 9.11.5, 10.0.x <= 10.0.3, 10.1.x <= 10.1.3 fail to properly validate post props which allows a malicious authenticated user to cause a crash via a malicious post.

BeyondTrust has patched all cloud instances of the vulnerability and has released patches for self-hosted versions.

Evidence suggests that some of the payloads and extensions may date as far back as April 2023.

"Operation 99" uses job postings to lure freelance software developers into downloading malicious Git repositories. From there, malware infiltrates developer projects to steal source code, secrets, and cryptocurrency.

Ultimately, there is no replacement for an intuitive, security-focused developer working with the critical thinking required to drive down the risk of both AI and human error.
