Scandal surrounding the Trump administration’s Signal group chat has led to a landmark week for the encrypted messaging app’s adoption—its “largest US growth moment by a massive margin.”

An Improper Link Resolution Before File Access ("Link Following") and Improper Limitation of a Pathname to a Restricted Directory ("Path Traversal"). This vulnerability occurs when extracting a maliciously crafted tar file, which can result in unauthorized file writes or overwrites outside the intended extraction directory. The issue is associated with index.js in the tar-fs package. This issue affects tar-fs: from 0.0.0 before 1.16.4, from 2.0.0 before 2.1.2, from 3.0.0 before 3.0.7.

An integer overflow in Nethermind Juno before v0.12.5 within the Sierra bytecode decompression logic within the "cairo-lang-starknet-classes" library could allow remote attackers to trigger an infinite loop (and high CPU usage) by submitting a malicious Declare v2/v3 transaction. This results in a denial-of-service condition for affected Starknet full-node implementations.

From @jackfromeast and @superboy-zjc: We have identified a class pollution vulnerability in Mesop (<= [0.14.0](https://github.com/mesop-dev/mesop/releases/tag/v0.14.0)) application that allows attackers to overwrite global variables and class attributes in certain Mesop modules during runtime. This vulnerability could directly lead to a denial of service (DoS) attack against the server. Additionally, it could also result in other severe consequences given the application's implementation, such as identity confusion, where an attacker could impersonate an assistant or system role within conversations. This impersonation could potentially enable jailbreak attacks when interacting with large language models (LLMs). Just like the Javascript's prototype pollution, this vulnerability could leave a way for attackers to manipulate the intended data-flow or control-flow of the application at runtime and lead to severe consequnces like RCE when gadgets are available.

### Impact A malicious server can craft events which, when received, prevent Synapse version up to 1.127.0 from federating with other servers. The vulnerability has been exploited in the wild. ### Patches Fixed in Synapse v1.127.1. ### Workarounds Closed federation environments of trusted servers or non-federating installations are not affected. ### For more information If you have any questions or comments about this advisory, please email us at [security at element.io](mailto:security@element.io).

Improper Control of Generation of Code ('Code Injection') vulnerability in Apache Kylin. If an attacker gets access to Kylin's system or project admin permission, the JDBC connection configuration maybe altered to execute arbitrary code from the remote. You are fine as long as the Kylin's system and project admin access is well protected. This issue affects Apache Kylin: from 4.0.0 through 5.0.1. Users are recommended to upgrade to version 5.0.2 or above, which fixes the issue.

Server-Side Request Forgery (SSRF) vulnerability in Apache Kylin. Through a kylin server, an attacker may forge a request to invoke "/kylin/api/xxx/diag" api on another internal host and possibly get leaked information. There are two preconditions: 1) The attacker has got admin access to a kylin server; 2) Another internal host has the "/kylin/api/xxx/diag" api endpoint open for service. This issue affects Apache Kylin: from 5.0.0 through 5.0.1. Users are recommended to upgrade to version 5.0.2, which fixes the issue.
