A flaw was found in the quarkus-resteasy extension, which causes memory leaks when client requests with low timeouts are made. If a client request times out, a buffer is not released correctly, leading to increased memory usage and eventual application crash due to OutOfMemoryError.

HaveIbeenPwned (HIBP) website has significantly expanded its database with hundreds of millions of newly compromised credentials extracted by hackers though infostealer logs.

Sweden’s proposal to mandate encryption backdoors faces backlash from Signal, cybersecurity experts, and even its military over privacy and security risks.

The Computer Emergency Response Team of Ukraine (CERT-UA) on Tuesday warned of renewed activity from an organized criminal group it tracks as UAC-0173 that involves infecting computers with a remote access trojan named DCRat (aka DarkCrystal RAT). The Ukrainian cybersecurity authority said it observed the latest attack wave starting in mid-January 2025. The activity is designed to target the

Cybersecurity researchers have flagged a malicious Python library on the Python Package Index (PyPI) repository that facilitates unauthorized music downloads from music streaming service Deezer. The package in question is automslc, which has been downloaded over 104,000 times to date. First published in May 2019, it remains available on PyPI as of writing. "Although automslc, which has been

### Summary In certain Subsonic API endpoints, authentication can be bypassed by using a non-existent username combined with an empty (salted) password hash. This allows read-only access to the server’s resources, though attempts at write operations fail with a “permission denied” error. ### Details A flaw in the authentication check process allows an attacker to specify any arbitrary username that does not exist on the system, along with a salted hash of an empty password. Under these conditions, Navidrome treats the request as authenticated, granting access to various Subsonic endpoints without requiring valid credentials. ### Proof of Concept (PoC) 1. Generate a random salt: ```javascript // e.g., salt = "x1vbudn1m6d" Math.random().toString(36).substring(2, 15) ``` 2. Calculate the MD5 hash of an empty password plus the salt: ```shell # Using the example salt above echo -n "x1vbudn1m6d" | md5sum 81f0c0fb5d202ab0d012e6eaeb722d79 - ``` 3. Send a re...

### Impact Only users that has configured a JupyterHub installation to use the authenticator class `LTI13Authenticator` are influenced. LTI13Authenticator that was introduced in `jupyterhub-ltiauthenticator` 1.3.0 wasn't validating JWT signatures. This is believed to allow the LTI13Authenticator to authorize a forged request granting access to existing and new user identities. ### Patches None. ### Workarounds None. ### References - [This code segment](https://github.com/jupyterhub/ltiauthenticator/blob/3feec2e81b9d3b0ad6b58ab4226af640833039f3/ltiauthenticator/lti13/validator.py#L122-L164) didn't validate a JWT signature.
