It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-88053 exists.\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-2026-88053/ (Markdown: https://insights.sbomify.com/CVE-2026-88053/index.md)","id":"CVE-2026-88053","markdown":"https://insights.sbomify.com/CVE-2026-88053/index.md","name":"CVE-2026-88053","record":{"aliases":["DEBIAN-CVE-2026-88053","ECHO-8957-f2f8-e53c","GHSA-rphx-x795-5qjv","UBUNTU-CVE-2026-88053","openSUSE-RU-2026:22002-1"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OCR engine library","requires_auth":"none","summary":"An attacker can cause heap corruption or potential code execution in Tesseract by providing a crafted .traineddata file with unvalidated counts.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"tesseract_ocr","vendor":"tesseract-ocr"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Tesseract is an open source OCR engine. In version 5.5.3 and earlier, Classify::ReadIntTemplates in src/classify/intproto.cpp reads NumClassPruners, NumClasses, and NumProtoSets from the TESSDATA_INTTEMP component of a crafted .traineddata file and uses those values as loop bounds without validating them against MAX_NUM_CLASS_PRUNERS, MAX_NUM_CLASSES, and MAX_NUM_PROTO_SETS. The loops store heap pointers into fixed-capacity ClassPruners and ProtoSets arrays in INT_TEMPLATES_STRUCT and INT_CLASS_STRUCT, so an oversized count causes heap out-of-bounds pointer writes during legacy-classifier initialization before OCR begins, resulting in heap corruption, a crash, or potentially controlled corruption. No fixed release is available as of this review.","ecosystems":["openSUSE:Leap 16.0"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Tesseract: Heap out-of-bounds write in Classify::ReadIntTemplates via unvalidated counts in crafted .traineddata","id":"CVE-2026-88053","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":1,"n_references":2,"next":{"headline":"Tesseract: Denial of service via empty-stack dereference in Plumbing/Series at model load","id":"CVE-2026-88054"},"packages":[{"ecosystem":"openSUSE:Leap 16.0","fixed":["5.5.3-bp160.2.1"],"introduced":["0"],"last_affected":[],"package":"tesseract-ocr","purl":"pkg:rpm/opensuse/tesseract-ocr\u0026distro=openSUSE%20Leap%2016.0","source":"openSUSE-RU-2026:22002-1"}],"prev":{"headline":"Tesseract: Heap out-of-bounds write in UNICHARSET::load_via_fgets via count/insert desynchronization","id":"CVE-2026-88052"},"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":7.8,"headline":"Tesseract: Heap out-of-bounds write in UNICHARSET::load_via_fgets via count/insert desynchronization","id":"CVE-2026-88052","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":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-11","vendors":["tesseract-ocr"]},"summary":"An attacker can cause heap corruption or potential code execution in Tesseract by providing a crafted .traineddata file with unvalidated counts.","url":"https://insights.sbomify.com/CVE-2026-88053/"}
