Deserialization Remote Code Execution
2026-03-18
A critical PHP object injection vulnerability exists in the Shinetheme Traveler WordPress theme due to insecure deserialization of untrusted data. This affects all versions prior to 3.2.8.1 and allows unauthenticated remote attackers to execute arbitrary code, compromise data confidentiality and integrity, and cause denial of service. The vulnerability has been publicly disclosed through Patchstack's database, though no active exploitation (KEV listing) or EPSS score data is currently available.
Remote code execution in the Beijing Academy of Artificial Intelligence (BAAI) OmniGen2-RL reward server lets unauthenticated attackers run arbitrary OS commands by POSTing a malicious pickle payload to the exposed HTTP endpoint. The reward_server.py and reward_proxy.py components call pickle.loads() directly on raw, attacker-controlled request bodies, so any network-reachable instance can be fully compromised. Publicly available exploit code exists (chocapikk.com write-up) and a vendor patch (PR #139) is available, though EPSS remains low at 0.13% and there is no public exploit identified as actively exploited.
