CVE-2026-42567
Svelte: ReDoS in `<svelte:element>` Tag Validation
發布日:2026/5/14修改日:2026/5/14
描述
An internal regex in the Svelte runtime can take exponential time to test in `<svelte:element this={tag}></svelte:element>`. You are only vulnerable to this if you allow tags of unconstrained length. If your application only allows a predetermined list of tags or trims their length before passing them to `svelte:element`, you are safe.
受影響套件(1)
- npm/svelte>= 5.51.5, < 5.55.7
