CVE-2026-52899n/a BigDL software before version Deserialization of Untrusted Data

NVD

Vulnerability Summary

Deserialization of untrusted data for some BigDL software before version 2.5.0b1 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via network access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
