Certificate-validation bypass in Eclipse Cyclone DDS before 0.10.5 lets unauthenticated network attackers defeat the DDS Security authentication plugin's certificate checks, and per the advisory execute commands with System privileges. The flaw stems from improper verification of certificate time/expiration (CWE-298), meaning expired or otherwise time-invalid certificates can be accepted as valid, enabling impersonation of trusted DDS participants. The EPSS score is low (0.30%, 22nd percentile) and there is no CISA KEV listing, so despite the maximal 10.0 CVSS there is no confirmed active exploitation at time of analysis.
An integer underflow during deserialization may allow any unauthenticated user to read out of bounds heap memory. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
