DEBIAN-CVE-2026-12484

A vulnerability in keras-team/keras version 3.15.0 allows unsafe deserialization of attacker-controlled PyTorch pickle data through the public keras.layers.TorchModuleWrapper.fromconfig method. This method invokes torch.load..., weightsonly=False without requiring an explicit unsafe opt-in, such ...

EUVD-2026-45276

IBM Langflow OSS 1.0.0 through 1.10.0 contain a critical remote code execution vulnerability in the disk-based caching mechanism. The AsyncDiskCache class uses Python's unsafe pickle.loads function to deserialize cached objects from disk without validation, integrity verification, or...

SGLang contains a vulnerable pickle deserialization vulnerability through the expert-parallel subsystem

Overview A Pickle deserialization vulnerability has been discovered within the SGLang project, enabling an attacker to perform remote code execution RCE on the target vulnerable server. In order for an attacker to exploit this vulnerability, the expert-parallel backup subsystem must be enabled, a...

PYSEC-2026-2389 BabelDOC: Arbitrary Code Execution via CMap Pickle Deserialization in babeldoc/pdfminer/cmapdb.py

Arbitrary Code Execution via CMap Pickle Deserialization in babeldoc/pdfminer/cmapdb.py Summary BabelDOC's vendored PDF parser babeldoc/pdfminer/cmapdb.py deserializes untrusted pickle data when loading CMap files. The loaddata method strips only NUL bytes from a PDF-controlled CMap name, then...

PYSEC-2026-2496 Glances has Insecure Pickle Deserialization in its Version Cache that Leads to Arbitrary Code Execution

Summary glances/outdated.py uses pickle.load to read a version-check cache file stored at a predictable, world-accessible path /.cache/glances/glances-version.db or $XDGCACHEHOME/glances/glances-version.db. No integrity check, signature verification, or format validation is performed before...

PYSEC-2026-3075 Stanza: Remote Code Execution via Unsafe Pickle Deserialization in Model Loaders

Summary Stanza 1.12.0 attempts to safely load PyTorch checkpoint files using torch.load..., weightsonly=True, but automatically falls back to the fully unsafe torch.load..., weightsonly=False when the safe load raises pickle.UnpicklingError. Because the UnpicklingError condition is fully...

PYSEC-2026-2477 flash-attention contains an insecure deserialization vulnerability in its checkpoint loading mechanism

The flash-attention training framework thru commit e724e2588cbe754beb97cf7c011b5e7e34119e62 2025-13-04 contains an insecure deserialization vulnerability CWE-502 in its checkpoint loading mechanism. The loadcheckpoint function in checkpoint.py and the checkpoint loading code in eval.py use...

PYSEC-2026-2445 DeepDiff has Memory Exhaustion DoS through SAFE_TO_IMPORT

Summary The pickle unpickler RestrictedUnpickler validates which classes can be loaded but does not limit their constructor arguments. A few of the types in SAFETOIMPORT have constructors that allocate memory proportional to their input builtins.bytes, builtins.list, builtins.range. A 40-byte...

PYSEC-2026-2367 Apache Airflow Providers Http has Unsafe Pickle Deserializatio leading to RCE via HttpOperator

A user with access to the DB could craft a database entry that would result in executing code on Triggerer - which gives anyone who have access to DB the same permissions as Dag Author. Since direct DB access is not usual and recommended for Airflow, the likelihood of it making any damage is low...

PYSEC-2026-2447 DiskCache has unsafe pickle deserialization

DiskCache python-diskcache through 5.6.3 uses Python pickle for serialization by default. An attacker with write access to the cache directory can achieve arbitrary code execution when a victim application reads from the cache...
