"details": "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.\n\nThis issue was discovered and patched during an code audit and penetration test of SurrealDB by cure53. Using CVSSv4 definitions, the severity is High. \n\n### Impact\nAn authenticated user can crash the SurrealDB instance through memory exhaustion\n\n### Patches\nA patch has been created that enforces a limit on string length `SURREAL_GENERATION_ALLOCATION_LIMIT`\n\n- Versions 2.0.5, 2.1.5, 2.2.2, and later are not affected by this issue\n\n### Workarounds\nAffected users who are unable to update may want to limit the ability of untrusted clients to run the `string::replace` function in the affected versions of SurrealDB using the `--deny-functions` flag described within [Capabilities](https://surrealdb.com/docs/surrealdb/security/capabilities#functions) or the equivalent `SURREAL_CAPS_DENY_FUNC` environment variable.\n\n### References\n\n[SurrealQL Documentation - DB Functions (string::replace)](https://surrealdb.com/docs/surrealql/functions/database/string#stringreplace)\n[SurrealDB Documentation - Capabilities](https://surrealdb.com/docs/surrealdb/security/capabilities#functions)\n[SurrealDB Documentation - Environment Variables](https://surrealdb.com/docs/surrealdb/cli/env)\n[#5619 ](https://github.com/surrealdb/surrealdb/pull/5619)\n[#5638 ](https://github.com/surrealdb/surrealdb/pull/5638)",

"details": "Through enabling the scripting capability. SurrealDB allows for advanced functions with complicated logic, by allowing embedded functions to be written in JavaScript.\n\nThese functions are bounded for memory and stack size, but not in time. An attacker could launch a number of long running functions that could potentially facilitate a Denial Of Service attack.\n\nThis vulnerability can only affect SurrealDB servers explicitly enabling the scripting capability with `--allow-scripting` or\n`--allow-all` and equivalent environment variables `SURREAL_CAPS_ALLOW_SCRIPT=true` and `SURREAL_CAPS_ALLOW_ALL=true`.\n\nThis issue was discovered and patched during an code audit and penetration test of SurrealDB by cure53, the severity defined within cure53's preliminary finding is Low, matched by our CVSS v4 assessment.\n\n### Impact\nAn attacker can use the scripting capabilities of SurrealDB to run a series of long running functions to facilitate a Denial Of Service attack.\n\n### Patches\nA default timeout for the scripting functions has been implemented with a configurable `SURREAL_SCRIPTING_MAX_TIME_LIMIT` environment variable\n\n- Versions 2.0.5, 2.1.5, 2.2.2 and later are not affected by this issue.\n\n### Workarounds\nFor users that cannot upgrade. Deny execution of embedded scripting functions through the configuration of [capabilities](https://surrealdb.com/docs/surrealdb/security/capabilities#capabilities) by starting SurrealDB with the `--deny-scripting` flag or the equivalent environment variable `SURREAL_CAPS_DENY_SCRIPT=true`. This has a usability implication, although scripting functions are disabled by default.\n\n### References\n[5597](https://github.com/surrealdb/surrealdb/pull/5597)\n[SurrealDB Documentation - Capabilities](https://surrealdb.com/docs/surrealdb/security/capabilities)\n[SurrealQL Documentation - Scripting Functions](https://surrealdb.com/docs/surrealql/functions/script)",
