Allocation of resources without limits or throttling, Initialization of a resource with an insecure default vulnerability in Apache Thrift Python bindings.
This issue affects Apache Thrift: before 0.25.0.
Users are recommended to upgrade to version 0.25.0, which fixes the issue.
Articles & Coverage 1
AnalysisAI
Denial of service in Apache Thrift's Python bindings (all versions before 0.25.0) allows remote, unauthenticated clients to force unbounded memory allocation by sending crafted messages that declare oversized containers or strings, crashing or hanging the affected service. The flaw pairs a missing resource limit with an insecure default configuration in which the bindings apply no read or container size cap unless the application explicitly sets one, so any network-reachable Thrift service that accepts untrusted traffic while running on those defaults is exposed. …

Vulnerability AssessmentAI
| Exploitation | Requires a network-reachable service built on the Apache Thrift Python bindings (before 0.25.0) that accepts messages from untrusted clients while running with the insecure default configuration lacking read/container size limits; the attacker then submits crafted messages declaring oversized containers or strings to force unbounded allocation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but bounded denial-of-service issue rather than a critical priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: upgrade Apache Thrift Python bindings to version 0.25.0, which fixes the issue; this is the primary and recommended action, and any service built on the bindings should be rebuilt and redeployed against the patched release. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every application that embeds Apache Thrift Python bindings and confirm which deployments are network-reachable from untrusted networks, then explicitly set message and container size limits (for example a maximum message size via the Thrift TConfiguration/maxMessageSize setting) in those services as a stopgap, since all versions before 0.25.0 are affected and no vendor patch is yet available. …
