CVE-2026-73411

Shescape is a simple shell escape library for JavaScript. Prior to 2.1.14 and 3.0.1, getEscapeFunction in src/internal/unix/dash.js fails to escape after : or = when applications use the escape or escapeAll APIs on Unix with shell set to dash, or with shell set to true when Dash is the default, a...

CVE-2026-73411

Vulnerability summary (CVE-2026-73411) : The Shescape JavaScript library is affected by a flaw in getEscapeFunction (src/internal/unix/dash.js) prior to versions 2.1.14 and 3.0.1. When using escape or escapeAll APIs on Unix with shell set to dash (or shell=true when Dash is default), the code fai...

CVE-2026-73411 Shescape: Home-directory disclosure in assignment context on Unix with Dash

Shescape is a simple shell escape library for JavaScript. Prior to 2.1.14 and 3.0.1, getEscapeFunction in src/internal/unix/dash.js fails to escape after : or = when applications use the escape or escapeAll APIs on Unix with shell set to dash, or with shell set to true when Dash is the default, a...

CVE-2026-6791

A flaw was found in glibc. When processing paths that start with a tilde followed by a username, the wordexp function can be forced to allocate an excessive amount of memory on the program's stack. A remote attacker could exploit this by providing a very long username, leading to a stack exhausti...

glibc: Glibc: Denial of Service via stack exhaustion during tilde expansion

A flaw was found in glibc. When processing paths that start with a tilde followed by a username, the wordexp function can be forced to allocate an excessive amount of memory on the program's stack. A remote attacker could exploit this by providing a very long username, leading to a stack exhausti...

DEBIAN-CVE-2026-6791

When expanding paths that begin with a tilde followed by a username, the internal parsetilde function extracts the username to determine the user's home directory. The implementation allocates memory for this username directly on the stack using the strndupa macro. Because the size of this...

UBUNTU-CVE-2026-6791

When expanding paths that begin with a tilde followed by a username, the internal parsetilde function extracts the username to determine the user's home directory. The implementation allocates memory for this username directly on the stack using the strndupa macro. Because the size of this...

CVE-2026-6791

CVE-2026-6791 concerns tilde expansion in wordexp within glibc. When expanding paths starting with ~username, parse_tilde extracts the username and allocates memory for it on the stack via strndupa. No bounds checks on the username length can exhaust stack space, enabling a stack-clash condition ...

GHSA-GM37-52C6-37MW pymdown-extensions: exponential-backtracking ReDoS in caret, tilde, betterem, and magiclink inline processors

Summary Four inline processors in pymdown-extensions contain regular expressions with exponential backtracking. A single untrusted Markdown line under 50 bytes drives markdown.markdown into unbounded CPU on the rendering thread seconds at 45 bytes, growing exponentially with each added character...

CVE-2026-67422

CVE-2026-67422 affects pymdown-extensions up to version 11.0, where four inline processors—caret, tilde, betterem, and magiclink—use regex patterns whose groups can partition delimiter runs in exponentially many ways. This causes catastrophic backtracking and unbounded CPU usage when rendering a ...
