GHSA-MHC9-48GJ-9GP3 Fickling has safety check bypass via REDUCE+BUILD opcode sequence
Assessment It is believed that the analysis pass works as intended, REDUCE and BUILD are not at fault here. The few potentially unsafe modules have been added to the blocklist https://github.com/trailofbits/fickling/commit/0c4558d950daf70e134090573450ddcedaf10400. Original report Summary All 5 of...

Interpretation Conflict
Overview fickling is an A static analyzer and interpreter for Python pickle data Affected versions of this package are vulnerable to Interpretation Conflict via the OBJ opcode handling logic. An attacker can evade safety checks by triggering a code path where OBJ pushes an ast.Call onto the...
Fickling: OBJ opcode call invisibility bypasses all safety checks
Assessment The interpreter so it behaves closer to CPython when dealing with OBJ, NEWOBJ, and NEWOBJEX opcodes https://github.com/trailofbits/fickling/commit/ff423dade2bb1f72b2b48586c022fac40cbd9a4a. Original report Summary All 5 of fickling's safety interfaces -- islikelysafe, checksafety, CLI...
Incomplete List of Disallowed Inputs
Overview fickling is an A static analyzer and interpreter for Python pickle data Affected versions of this package are vulnerable to Incomplete List of Disallowed Inputs in the checksafety function. An attacker can trigger outbound TCP connections during deserialization by crafting malicious pick...
Insecure Deserialization
fickling is vulnerable to Insecure Deserialization. The vulnerability is due to Fickling not treating Python’s runpy module as unsafe, which allows an attacker to craft a malicious pickle using runpy.runpath or runpy.runmodule that is misclassified as suspicious rather than overtly malicious,...
CVE-2026-22607
Fickling is a Python pickling decompiler and static analyzer. Fickling versions up to and including 0.1.6 do not treat Python's cProfile module as unsafe. Because of this, a malicious pickle that uses cProfile.run is classified as SUSPICIOUS instead of OVERTLYMALICIOUS. If a user relies on...
CVE-2026-22612
Fickling is a Python pickling decompiler and static analyzer. Prior to version 0.1.7, Fickling is vulnerable to detection bypass due to "builtins" blindness. This issue has been patched in version 0.1.7...
CVE-2026-22609
Fickling is a Python pickling decompiler and static analyzer. Prior to version 0.1.7, the unsafeimports method in Fickling's static analyzer fails to flag several high-risk Python modules that can be used for arbitrary code execution. Malicious pickles importing these modules will not be detected...
CVE-2026-22606
Fickling is a Python pickling decompiler and static analyzer. Fickling versions up to and including 0.1.6 do not treat Python’s runpy module as unsafe. Because of this, a malicious pickle that uses runpy.runpath or runpy.runmodule is classified as SUSPICIOUS instead of OVERTLYMALICIOUS. If a user...
CVE-2026-22608
Fickling is a Python pickling decompiler and static analyzer. Prior to version 0.1.7, both ctypes and pydoc modules aren't explicitly blocked. Even other existing pickle scanning tools like picklescan do not block pydoc.locate. Chaining these two together can achieve RCE while the scanner still...

CVE-2026-22612
Summary of CVE-2026-22612 : Fickling (Python pickling decompiler/static analyzer) before version 0.1.7 is vulnerable to a detection bypass caused by “builtins” blindness. This allows crafted pickle payloads to bypass security analysis, as shown by example payloads that construct and execute code ...
