7.1 highCVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:HCVE-2026-42476
High (7.1) in opencascade open cascade technology. EPSS 0.1% chance of exploitation in the next 30 days.
Two heap-based out-of-bounds read vulnerabilities in the STL ASCII file parser in Open CASCADE Technology (OCCT) V8_0_0_rc5 exist in RWStl_Reader::ReadAscii because buffers returned by Standard_ReadLineBuffer::ReadLine() are not properly length-validated before strncasecmp or direct byte access. User-assisted attackers can trigger these issues by persuading a victim to open a crafted STL file with extremely short lines, resulting in a denial of service or possible information disclosure.
