CVE-2026-88368
High 7.5
In plain English
A high-severity security flaw in the nanosvg package (Ubuntu). Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 33% of all known vulnerabilities).
Official description
NanoSVG commit 239e102ec contains an incorrect numeric conversion vulnerability in the rasterizer's nsvg__addActive() function. A specially crafted SVG document containing sufficiently large geometry coordinates can cause fixed-point-scaled edge coordinates to exceed the range representable by int. The rasterizer subsequently converts these values to int without range validation, resulting in undefined behavior and possible process termination, leading to denial of service.
