A vulnerability has been found in OpenBankProject OBP-API up to 1.10.1. This impacts the function KryoInjection.invert of the file obp-api/src/main/scala/code/api/cache/Redis.scala of the component Kryo Handler. Such manipulation leads to deserialization. The attack can be launched remotely. A high complexity level is associated with this attack. The exploitability is said to be difficult. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.

Why it matters

Internet-facing
Not identified as a common internet-facing category
Exploitation likelihood
medium
  • Remotely exploitable over the network — no physical or local access required
  • High attack complexity — exploitation requires specific conditions
  • Requires high-privilege access first
  • No user interaction needed — can be exploited automatically
Recommended mitigation

Apply the vendor patch as soon as it's available or already released. Review and restrict accounts with the privilege level this vulnerability requires.

This analysis is generated from structured CVSS vector data, CISA KEV cross-referencing, and vendor/product category rules — not a manual expert review. Treat it as a starting point, not a substitute for your own assessment.
