It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-88052 in the wild and no public exploit code.\n\nAffected product: tesseract-ocr tesseract. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-88052/ (Markdown: https://insights.sbomify.com/CVE-2026-88052/index.md)","id":"CVE-2026-88052","markdown":"https://insights.sbomify.com/CVE-2026-88052/index.md","name":"CVE-2026-88052","record":{"aliases":["DEBIAN-CVE-2026-88052","ECHO-43ed-bd73-2a27","GHSA-2hm8-q5c7-c373","UBUNTU-CVE-2026-88052"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OCR engine library","requires_auth":"none","summary":"Heap out-of-bounds write in Tesseract OCR allows attackers to cause crashes or potentially execute code via crafted unicharset files.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"tesseract_ocr","vendor":"tesseract-ocr"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-129","name":"Improper Validation of Array Index"}],"description":"Tesseract is an open source OCR engine. In version 5.5.3 and earlier, UNICHARSET::load_via_fgets in src/ccutil/unicharset.cpp trusts the declared unichar count as a loop bound and uses id as an unchecked index into the unichars vector. unichar_insert_backwards_compatible can leave the vector unchanged for an empty, duplicate, or already-encodable representation, causing id to become larger than unichars.size(). Subsequent set_* calls and the write to unichars[id].properties.enabled then write UNICHAR_PROPERTIES beyond the vector during initialization in both the default LSTM and legacy engines, causing heap corruption, a crash, or potentially controlled corruption. No fixed release is available as of this review.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Tesseract: Heap out-of-bounds write in UNICHARSET::load_via_fgets via count/insert desynchronization","id":"CVE-2026-88052","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Tesseract: Heap out-of-bounds write in Classify::ReadIntTemplates via unvalidated counts in crafted .traineddata","id":"CVE-2026-88053"},"packages":[],"prev":{"headline":"Tesseract: Heap out-of-bounds write in GenericVector\u003cT\u003e::read due to independent reserved/size_used_ fields","id":"CVE-2026-88051"},"products":["tesseract"],"published":"2026-09-10","related":[{"cvss_score":8.6,"headline":"Tesseract: ReadNormProtos stack buffer overflow","id":"CVE-2026-88047","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.6,"headline":"Tesseract: Heap out-of-bounds write/read in FullyConnected::Forward via layer/weight-matrix dimension mismatch","id":"CVE-2026-88048","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.6,"headline":"Tesseract: Heap out-of-bounds write in LSTM::Forward via na_/gate-matrix dimension mismatch","id":"CVE-2026-88049","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.6,"headline":"Tesseract: Heap out-of-bounds write in GenericVector\u003cT\u003e::read due to independent reserved/size_used_ fields","id":"CVE-2026-88051","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.6,"headline":"Tesseract: Heap out-of-bounds write in Classify::ReadIntTemplates via unvalidated counts in crafted .traineddata","id":"CVE-2026-88053","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":7.8,"headline":"Use after free in n/a","id":"CVE-2021-36081","kev_date_added":null,"published":"2021-07-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-11","vendors":["tesseract-ocr"]},"summary":"Heap out-of-bounds write in Tesseract OCR allows attackers to cause crashes or potentially execute code via crafted unicharset files.","url":"https://insights.sbomify.com/CVE-2026-88052/"}
