Prior to 5.12.8 and 5.13.2, the PacketsApi.exportPackets endpoint in yamcs-core/src/main/java/org/yamcs/http/api/PacketsApi.java failed to enforce object-level ReadPacket privileges when a request omitted specific packet names: with an empty name list the ctx.checkObjectPrivileges(ObjectPrivilegeType.ReadPacket, nameSet) call passed over an empty set, no WHERE pname IN filter was applied to the resulting SELECT * FROM tm query, and the onTuple handler streamed every retrieved packet without any per-row authorization check, so a low-privileged or zero-privilege authenticated user could dump the entire raw telemetry packet archive and bypass the role-based access control model. This issue is fixed in versions 5.12.8 and 5.13.2, which enforce per-packet ReadPacket checks in exportPackets.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-284","CWE-862"],"references":["https://github.com/yamcs/yamcs/commit/b566beceba98cc35514b0e1519be126b8c5a0438","https://github.com/yamcs/yamcs/commit/c743cc3acf5b5c53ff5181b94eacc21340f70dd9","https://github.com/yamcs/yamcs/releases/tag/yamcs-5.12.8","https://github.com/yamcs/yamcs/releases/tag/yamcs-5.13.2","https://github.com/yamcs/yamcs/security/advisories/GHSA-8xjq-pr36-ccgf"],"products":["spaceapplications:yamcs"],"source":"nvd","synced_at":"2026-10-19T22:45:36.895656543+00:00"},"epss":{"cve":"CVE-2026-55548","score":0.0036,"percentile":0.29844,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-8xjq-pr36-ccgf","url":"https://osv.dev/vulnerability/GHSA-8xjq-pr36-ccgf","summary":"Yamcs: Insecure Direct Object Reference (IDOR) in PacketsApi allows unprivileged users to dump all telemetry packets","modified":"2026-08-28T17:30:07.755157121Z","packages":[{"ecosystem":"Maven","name":"org.yamcs:yamcs-core","purl":"pkg:maven/org.yamcs/yamcs-core","ranges":[">=5.13.0 <5.13.2"],"fixed":["5.13.2"]},{"ecosystem":"Maven","name":"org.yamcs:yamcs-core","purl":"pkg:maven/org.yamcs/yamcs-core","ranges":["<5.12.8"],"fixed":["5.12.8"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
