OCaml Security Advisory Database 安全漏洞

The OCaml Security Advisory Database is a security database developed under the open-source OCaml language. Versions prior to 4.14.3 and 5.x versions before 5.4.1 of the OCaml Security Advisory Database contain security vulnerabilities. These vulnerabilities stem from excessive buffer reading...

golang: html/template: errors returned from MarshalJSON methods may break template escaping

A flaw was found in Go's html/template standard library package. If errors returned from MarshalJSON methods contain user-controlled data, they may be used to break the contextual auto-escaping behavior of the html/template package, allowing subsequent actions to inject unexpected content into...

OSEC-2026-01 Buffer Over-Read in OCaml Marshal Deserialization

Summary A critical buffer over-read vulnerability in OCaml's Marshal deserialization runtime/intern.c enables remote code execution through a multi-phase attack chain. The vulnerability stems from missing bounds validation in the readblock function, which performs unbounded memcpy operations usin...

PT-2026-22292

Name of the Vulnerable Software and Affected Versions OCaml versions prior to 4.14.3 and 5.x versions prior to 5.4.1 Description A flaw exists in OCaml's Marshal deserialization process within runtime/intern.c that could allow for remote code execution. This issue stems from a missing bounds chec...

Insecure Deserialization

Fickling is vulnerable to Insecure Deserialization. The vulnerability is due to missing marshal and types modules from the unsafe import block list, which allows an attacker to craft a malicious pickle file that bypasses Fickling’s analysis and executes arbitrary code when deserialized by a...

CVE-2025-67747

Fickling is a Python pickling decompiler and static analyzer. Versions prior to 0.1.6 are missing marshal and types from the block list of unsafe module imports. Fickling started blocking both modules to address this issue. This allows an attacker to craft a malicious pickle file that can bypass...
