An authenticated user can craft a query using the `string::replace` function that uses a Regex to perform a string replacement. As there is a failure to restrict the resulting string length, this enables an attacker to send a `string::replace` function to the SurrealDB server exhausting all the memory of the server due to string allocations. This eventually results in a Denial-of-Service situation for the SurrealDB server. This issue was discovered and patched during an code audit and penetration test of SurrealDB by cure53. Using CVSSv4 definitions, the severity is High. ### Impact An authenticated user can crash the SurrealDB instance through memory exhaustion ### Patches A patch has been created that enforces a limit on string length `SURREAL_GENERATION_ALLOCATION_LIMIT` - Versions 2.0.5, 2.1.5, 2.2.2, and later are not affected by this issue ### Workarounds Affected users who are unable to update may want to limit the ability of untrusted clients to run the `string::replace`...

A vulnerability was found where an attacker can crash the database via crafting a HTTP query that returns a null byte. The problem relies on an uncaught exception in the `net` module, where the result of the query will be converted to JSON before showing as the HTTP response to the user in the **/sql** endpoint. ### Impact This vulnerability allows any authenticated user to crash a SurrealDB instance by sending a crafted query with a null byte to the /sql endpoint. Where SurrealDB is used as an application backend, it is possible that an application user can crash the SurrealDB instance and thus the supported application through crafted inputs that exploit this attack vector. ### Patches A patch has been introduced that ensures the error is caught and converted as an error. - Versions 2.2.2, 2.1.5 and 2.0.5 and later are not affected by this isssue ### Workarounds Affected users who are unable to update may want to limit the ability of untrusted clients to run arbitrary queries ...

### Summary Xgrammar includes a cache for compiled grammars to increase performance with repeated use of the same grammar. This cache is held in memory. Since the cache is unbounded, a system making use of xgrammar can be abused to fill up a host's memory and case a denial of service. For example, sending many small requests to an LLM inference server with unique JSON schemas would eventually cause this denial of service to occur. ### Details The fix is to add a limit to the cache size. This was done in https://github.com/mlc-ai/xgrammar/pull/243 An example of making use of the new cache size limit can be found in vLLM here: https://github.com/vllm-project/vllm/pull/16283 ### Impact Any system making use of Xgrammar and taking requests as input from potentially untrusted parties would be vulnerable to this denial of service issue.

### Impact The buffer created for parsing metadata for PNG and WebP images was only bounded by their input data type, which could lead to potentially large memory allocation, and unreasonably high for image metadata. Before `v0.11.0`, If you didn't trust the input images, this could be abused to construct denial-of-service attacks. ### Patches `v0.11.0` added a 10 MB upper limit.

### Impact The EXIF data format allows for defining excessively large data structures in relatively small payloads. Before `v0.10.0`, If you didn't trust the input images, this could be abused to construct denial-of-service attacks. ### Patches `v0.10.0` added LimitNumTags (default 5000) and LimitTagSize (default 10000) options.

### Impact It's possible to pass long passwords that leads to Denial Of Service via forms in Storefront forms or Store-API. ### Patches Update to Shopware 6.6.10.3 or 6.5.8.17 ### Workarounds For older versions of 6.4, corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version.
