Last modified

CVE-2026-73067 is a medium-severity vulnerability rated 6.7/10 on the CVSS scale. Tesseract is an open source OCR engine. Prior to 5.5.3, a crafted .traineddata model loaded through TessBaseAPI::Init can cause SquishedDawg::read_squished_dawg in src/dict/dawg.cpp to accept an unterminated forward-edge run, after which SquishedDawg::Load calls num_forward_edges(0) and last_edge in src/dict/dawg.h reads beyond edges_, causing a heap out-of-bounds read and process crash before image processing. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
