datapizza-ai: Deserialization of Untrusted Data
CVE-2026-2970 is a high-severity deserialization of untrusted data vulnerability in datapizza-ai from Datapizza-labs, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. Affected datapizza-ai versions: 0.0.2. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.73% chance of exploitation within 30 days, higher than 55% of scored CVEs.
High severity with no evidence of exploitation so far.

Official description
A vulnerability has been found in datapizza-labs datapizza-ai 0.0.2. Affected by this vulnerability is the function RedisCache of the file datapizza-ai-cache/redis/datapizza/cache/redis/cache.py. Such manipulation leads to deserialization. The attack requires being on the local network. A high complexity level is associated with this attack. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

The underlying weakness: Deserialization of Untrusted Data
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
How developers prevent this class of flaw
- If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
- When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
- Explicitly define a final object() to prevent deserialization.
