An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-22697 exists.\n\nAffected product: nasa CryptoLib. 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-2026-22697/ (Markdown: https://insights.sbomify.com/CVE-2026-22697/index.md)","id":"CVE-2026-22697","markdown":"https://insights.sbomify.com/CVE-2026-22697/index.md","name":"CVE-2026-22697","record":{"aliases":["GHSA-qjx3-83jh-2jc4"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Space Data Link Security Library","requires_auth":"none","summary":"Heap buffer overflow in CryptoLib's KMC Base64 decoding allows attackers to cause crashes or execute code via oversized Base64 strings.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"cryptolib","vendor":"nasa"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.3, CryptoLib’s KMC crypto service integration is vulnerable to a heap buffer overflow when decoding Base64-encoded ciphertext/cleartext fields returned by the KMC service. The decode destination buffer is sized using an expected output length (len_data_out), but the Base64 decoder writes output based on the actual Base64 input length and does not enforce any destination size limit. An oversized Base64 string in the KMC JSON response can cause out-of-bounds writes on the heap, resulting in process crash and potentially code execution under certain conditions. This issue has been patched in version 1.4.3.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Memory corruption in CryptoLib","id":"CVE-2026-22697","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":"RustCrypto SM2-PKE has 32-bit Biased Nonce Vulnerability","id":"CVE-2026-22698"},"packages":[],"prev":{"headline":"dcap-qvl has Missing Verification for QE Identity","id":"CVE-2026-22696"},"products":["CryptoLib"],"published":"2026-01-10","related":[{"cvss_score":9.4,"headline":"CryptoLib Has Heap Overflow in Crypto_TM_ProcessSecurity due to Unchecked Secondary Header Length","id":"CVE-2025-30216","kev_date_added":null,"published":"2025-03-25"},{"cvss_score":9.3,"headline":"Heap Buffer Overflow via Incomplete Length Check in `Crypto_TC_ApplySecurity`","id":"CVE-2025-30356","kev_date_added":null,"published":"2025-04-01"},{"cvss_score":8.9,"headline":"CryptoLib's Crypto_TC_ApplySecurity() Has a Heap Buffer Overflow Vulnerability","id":"CVE-2025-29909","kev_date_added":null,"published":"2025-03-17"},{"cvss_score":8.9,"headline":"CryptoLib Has Heap Buffer Overflow in Crypto_AOS_ProcessSecurity Function","id":"CVE-2025-29911","kev_date_added":null,"published":"2025-03-17"},{"cvss_score":8.9,"headline":"CryptoLib Has Heap Buffer Overflow Due to Unsigned Integer Underflow in Crypto_TC_ProcessSecurity","id":"CVE-2025-29912","kev_date_added":null,"published":"2025-03-17"},{"cvss_score":8.9,"headline":"CryptoLib's Crypto_TC_Prep_AAD Has Buffer Overflow Due to Integer Underflow","id":"CVE-2025-29913","kev_date_added":null,"published":"2025-03-17"},{"cvss_score":8.8,"headline":"CryptoLib vulnerable to Stack Buffer Overflow in Crypto_Key_Update due to missing TLV length check","id":"CVE-2025-64096","kev_date_added":null,"published":"2025-10-30"}],"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-01-13","vendors":["nasa"]},"summary":"Heap buffer overflow in CryptoLib's KMC Base64 decoding allows attackers to cause crashes or execute code via oversized Base64 strings.","url":"https://insights.sbomify.com/CVE-2026-22697/"}
