      <title>CVE-2026-55548 — Yamcs: Insecure Direct Object Reference (IDOR) in PacketsApi allows unprivileged users to dump all telemetry packets</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-55548</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; yamcs&lt;/p&gt;
&lt;p&gt;Yamcs is a mission control framework. 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.&lt;/p&gt;</description>
