CVE-2026-73067Public exploit

Process crash via unterminated DAWG edge run

Published Aug 11, 2026 · Updated Aug 11, 2026

Out-of-bounds read in Tesseract before 5.5.3 allows local users to crash the process by loading a crafted .traineddata model. SquishedDawg::read_squished_dawg accepts an unterminated forward-edge run, and last_edge then indexes edges_ without checking the declared edge count. Exploitation requires an untrusted model to reach TessBaseAPI::Init; the bounded consequence is a crash before image processing, with no reported data disclosure.
