A flaw was found in the Keycloak identity and access management system when Fine-Grained Admin Permissions (FGAPv2) are enabled. An administrative user with the manage-users role can escalate their privileges to realm-admin due to improper privilege enforcement. This vulnerability allows unauthorized elevation of access rights, compromising the intended separation of administrative duties and posing a security risk to the realm.

A new report traces the history of the early wave of Chinese hackers who became the backbone of the state's espionage apparatus.

Mattermost versions 10.5.x <= 10.5.6, 10.8.x <= 10.8.1, 10.7.x <= 10.7.3, 9.11.x <= 9.11.16 fail to verify authorization when retrieving cached posts by PendingPostID which allows an authenticated user to read posts in private channels they don't have access to via guessing the PendingPostID of recently created posts.

An open redirect vulnerability has been identified in Grafana OSS that can be exploited to achieve XSS attacks. The vulnerability was introduced in Grafana v11.5.0. The open redirect can be chained with path traversal vulnerabilities to achieve XSS. Fixed in versions 12.0.2+security-01, 11.6.3+security-01, 11.5.6+security-01, 11.4.6+security-01 and 11.3.8+security-01

Security researchers recently revealed that the personal information of millions of people who applied for jobs at McDonald's was exposed after they guessed the password ("123456") for the fast food chain's account at Paradox.ai, a company that makes artificial intelligence based hiring chatbots used by many Fortune 500 companies. Paradox.ai said the security oversight was an isolated incident that did not affect its other customers, but recent security breaches involving its employees in Vietnam tell a more nuanced story.

### Impact A bug in on-headers versions `< 1.1.0` may result in response headers being inadvertently modified when an array is passed to `response.writeHead()` ### Patches Users should upgrade to `1.1.0` ### Workarounds Uses are encouraged to upgrade to `1.1.0`, but this issue can be worked around by passing an object to `response.writeHead()` rather than an array.

### Impact A vulnerability in Multer versions >= 1.4.4-lts.1, < 2.0.2 allows an attacker to trigger a Denial of Service (DoS) by sending a malformed request. This request causes an unhandled exception, leading to a crash of the process. ### Patches Users should upgrade to `2.0.2` ### Workarounds None

### Impact In Livewire v3 (≤ 3.6.3), a vulnerability allows unauthenticated attackers to achieve remote command execution in specific scenarios. The issue stems from how certain component property updates are hydrated. This vulnerability is unique to Livewire v3 and does not affect prior major versions. Exploitation requires a component to be mounted and configured in a particular way, but does not require authentication or user interaction. ### Patches This issue has been patched in Livewire v3.6.4. All users are strongly encouraged to upgrade to this version or later as soon as possible. ### Workarounds There is no known workaround at this time. Users are strongly advised to upgrade to a patched version immediately. ### Resources No public references available at this time to avoid exposure. Details will be published after a responsible disclosure window.

Texas adoption agency suffers major data leak, exposing over 1.1M sensitive records including case notes, contact info, and internal communications to public without any security authentication or password.

### Summary An attacker can forge a request to redirect an authenticated user to any arbitrary website. ### Details On the login page, we have a `redirect` field which is the location where the server will redirect the user. This URI is not verified, and can be an arbitrary URI. Paired with a parameter pollution, we can hide our malicious URI (ex: `https://dns.com/?param1=im_hidden_if_theres_lot_of_args?param1=bbb`). ### PoC https://diracx-cert.app.cern.ch/auth?redirect=https://ipcim.com/en/where/?dsdsd=qsqsfsjfnsfniizaeiaapzqlalkqkaizqqijsjaopmqmxna?redirect=https://diracx-cert-app.cern.ch/auth This POC can leak user's position. ### Impact This could be used for phishing and extracting new data (such as redirecting to a new "log in" page, and asking users to reenter credentials).
