It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-16459 in the wild and no public exploit code.\n\nAffected product: Oberon PSA Crypto. 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-2026-16459/ (Markdown: https://insights.sbomify.com/CVE-2026-16459/index.md)","id":"CVE-2026-16459","markdown":"https://insights.sbomify.com/CVE-2026-16459/index.md","name":"CVE-2026-16459","record":{"aliases":["GHSA-f34q-f47h-v25c"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Oberon PSA Crypto library","requires_auth":"none","summary":"Attackers can recover plaintexts from RSA PKCS#1 v1.5 decryption via timing side-channel attacks in the Oberon PSA Crypto library.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NCSC.ch","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"},{"id":"CWE-208","name":"Observable Timing Discrepancy"}],"description":"Padding oracle attack vulnerability in Oberon microsystem AG’s Oberon PSA Crypto library in all versions since 1.0.0 and prior to 2.1.1 allows an attacker to recover plaintexts via timing measurements of RSA PKCS#1 v1.5 decrypt operations.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Timing side-channel in RSA PKCS#1 v1.5 decryption in Oberon PSA Crypto","id":"CVE-2026-16459","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Bootc: ostree: bootc/ostree: staged deployments not revalidated against container signature policy before finalization","id":"CVE-2026-16460"},"packages":[],"prev":{"headline":"Timing side-channel in RSA PKCS#1 v1.5 decryption in ocrypto","id":"CVE-2026-16458"},"products":["Oberon PSA Crypto"],"published":"2026-08-13","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":"2026-08-13","vendors":["Oberon microsystems AG"]},"summary":"Attackers can recover plaintexts from RSA PKCS#1 v1.5 decryption via timing side-channel attacks in the Oberon PSA Crypto library.","url":"https://insights.sbomify.com/CVE-2026-16459/"}
