A Regular Expression Denial of Service (ReDoS) vulnerability was discovered in the Hugging Face Transformers library, specifically within the DonutProcessor class's `token2json()` method. This vulnerability affects versions 4.51.3 and earlier, and is fixed in version 4.52.1. The issue arises from the regex pattern `<s_(.*?)>` which can be exploited to cause excessive CPU consumption through crafted input strings due to catastrophic backtracking. This vulnerability can lead to service disruption, resource exhaustion, and potential API service vulnerabilities, impacting document processing tasks using the Donut model.

Connect2id Nimbus JOSE + JWT before 10.0.2 allows a remote attacker to cause a denial of service via a deeply nested JSON object supplied in a JWT claim set, because of uncontrolled recursion. NOTE: this is independent of the Gson 2.11.0 issue because the Connect2id product could have checked the JSON object nesting depth, regardless of what limits (if any) were imposed by Gson.

Uncontrolled Resource Consumption vulnerability in Apache Tomcat if an HTTP/2 client did not acknowledge the initial settings frame that reduces the maximum permitted concurrent streams. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.8, from 10.1.0-M1 through 10.1.42, from 9.0.0.M1 through 9.0.106. Users are recommended to upgrade to version 11.0.9, 10.1.43 or 9.0.107, which fix the issue.

### Impact The HTTP Gateway processes headers, but with no timeout set. With a Slowloris attack, an attacker could cause Denial of Service (DoS). Exploitation does not require authentication nor authorization, so anyone can exploit it. It should nonetheless not be exploitable as it is highly recommended to bury Chall-Manager deep within the infrastructure due to its large capabilities, so no users could reach the system. ### Patches Patch has been implemented by [commit `1385bd8`](https://github.com/ctfer-io/chall-manager/commit/1385bd869142651146cd0b123085f91cec698636) and shipped in [`v0.1.4`](https://github.com/ctfer-io/chall-manager/releases/tag/v0.1.4). ### Workarounds No workaround exist. ### References N/A

### Summary Sending a message that modifies the validator set at the epoch boundary halts the chain. ### Impact Denial of Service - Comos-sdk prevents modifying the validator set from two different modules - https://github.com/cosmos/cosmos-sdk/blob/release/v0.50.x/types/module/module.go#L811. Such an operation leads to panic and chain halt. ### Detailed Post mortem https://boiling-lake-106.notion.site/2025-06-18-Genesis-mainnet-chain-halt-post-mortem-229f60cc1b5f80b7adf5e3ea0541ea87

Out-of-bounds read in Windows Kerberos allows an authorized attacker to deny service over a network.

**According to the CVSS score, the attack vector is adjacent (AV:A). What does this mean for this vulnerability?** This attack is limited to systems connected to the same network segment as the attacker. The attack cannot be performed across multiple networks (for example, a WAN) and would be limited to systems on the same network switch or virtual network.
