Memory Limit Bypass

LiquidJS is vulnerable to Memory Limit Bypass. The vulnerability is due to the replace filter incorrectly accounting for memory usage when the memoryLimit option is enabled, where an attacker who controls template content can bypass the memoryLimit DoS protection with approximately 2,500x...

CVE-2026-35034 Jellyfin: Potential Application DoS from excessively large SyncPlay group names

Jellyfin is an open source self hosted media server. Versions prior to 10.11.7 contain a denial of service vulnerability in the SyncPlay group creation endpoint POST /SyncPlay/New, where an authenticated user can create groups with names of unlimited size due to insufficient input validation. By...

golang: archive/zip: Excessive CPU consumption when building archive index in archive/zip

A flaw was found in the archive/zip package in the Go standard library. A super-linear file name indexing algorithm is used in the first time a file in an archive is opened. A crafted zip archive containing a specific arrangement of file names can cause an excessive CPU and memory consumption. A ...

undici: Undici: Denial of Service due to uncontrolled resource consumption

A flaw was found in Undici. When the interceptors.deduplicate feature is enabled, response data for deduplicated requests can accumulate in memory. A remote attacker, by sending large or chunked responses and concurrent identical requests from an untrusted endpoint, can exploit this uncontrolled...

brace-expansion: brace-expansion: Denial of Service via unbounded brace range expansion

A flaw was found in the brace-expansion component. This denial of service DoS vulnerability allows a remote attacker to provide specially crafted input containing repeated numeric brace ranges. This input causes the library to attempt an unbounded expansion, consuming excessive CPU and memory...
