Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-7836 in the wild and no public exploit code.\n\nAffected product: Netatalk. 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-2026-7836/ (Markdown: https://insights.sbomify.com/CVE-2026-7836/index.md)","id":"CVE-2026-7836","markdown":"https://insights.sbomify.com/CVE-2026-7836/index.md","name":"CVE-2026-7836","record":{"aliases":["DEBIAN-CVE-2026-7836","GHSA-766c-rr8x-xjvp","UBUNTU-CVE-2026-7836"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Netatalk file server","requires_auth":"low_privilege","summary":"A remote authenticated attacker can cause limited data modification in Netatalk via crafted hexadecimal input due to a macro calculation error.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"securin","cpe":[],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-682","name":"Incorrect Calculation"}],"description":"An incorrect calculation in the hextoint macro in Netatalk 2.0.0 through 4.4.2 due to improper uppercase character handling allows a remote authenticated attacker to cause limited data modification via crafted hexadecimal input.","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":"hextoint macro uppercase bug","id":"CVE-2026-7836","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"TOCTOU with root privilege in ad_flush","id":"CVE-2026-7837"},"packages":[],"prev":{"headline":"Format string argument mismatch","id":"CVE-2026-7835"},"products":["Netatalk"],"published":"2026-05-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-05-21","vendors":["Netatalk"]},"summary":"A remote authenticated attacker can cause limited data modification in Netatalk via crafted hexadecimal input due to a macro calculation error.","url":"https://insights.sbomify.com/CVE-2026-7836/"}
