XonshActivator Code Execution

The vulnerability of the quote function in the XonshActivator class, a tool for creating isolated virtual environments in Python’s virtualenv, is related to improper code generation due to the use of outdated multi-byte encoding. Exploiting this vulnerability could allow an attacker to execute...

CVE-2026-114114 Vyper through 0.5.0b1 Literal Value Substitution via Multi-byte Characters

Vyper 0.1.0b1 before 0.1.0b12, 0.1.0b14, and 0.4.1 through 0.5.0b1 mix character-based line offsets with Python's UTF-8 byte coloffset values in vyper/ast/parse.py, so multi-byte characters shift the source slices used to reconstruct later numeric literals. An attacker contributing source with...

CVE-2026-114114

The Vyper smart contract programming language (versions 0.1.0b1 before 0.1.0b12, 0.1.0b14, and 0.4.1 through 0.5.0b1) is vulnerable to literal value substitution due to improper handling of Unicode encoding in vyper/ast/parse.py. The root cause is the mixing of character-based line offsets with P...

CVE-2026-114114 Vyper through 0.5.0b1 Literal Value Substitution via Multi-byte Characters

Vyper 0.1.0b1 before 0.1.0b12, 0.1.0b14, and 0.4.1 through 0.5.0b1 mix character-based line offsets with Python's UTF-8 byte coloffset values in vyper/ast/parse.py, so multi-byte characters shift the source slices used to reconstruct later numeric literals. An attacker contributing source with...

dovecot: Dovecot: MySQL multi-byte escaping wrong

A flaw was found in Dovecot. A remote attacker with high attack complexity could exploit this vulnerability to gain access to sensitive information and modify data without requiring any user interaction or privileges...

CVE-2026-100505 Ghidra 9.2 through 12.1.4 Heap Out-of-Bounds Read via StringManager

Ghidra versions 9.2 through 12.1.4 contain a heap out-of-bounds read vulnerability in StringManager::getCodepoint when decoding multi-byte UTF-8, UTF-16, or UTF-32 characters without validating remaining buffer length. Attackers can craft malicious binaries containing strings or constant byte...

MariaDB has possible SQL injection in Buffer parameter escaping under big5/gbk/sjis/cp932/gb18030 client charsets

Summary A SQL injection is possible when the connector escapes Buffer parameters client-side under a multi-byte client character set whose trail-byte range overlaps the ASCII backslash 0x5C: big5, gbk, sjis, cp932, and gb18030. Under these charsets, an attacker-controlled lead byte can absorb the...

Improper Encoding or Escaping of Output

Overview Affected versions of this package are vulnerable to Improper Encoding or Escaping of Output in the client-side escaping of Buffer parameters under certain multi-byte client character sets, specifically big5, gbk, sjis, cp932, or gb18030. An attacker can gain unauthorized access to or...

CVE-2026-52731 ZEBRA: Full node denial of service via non-ASCII LongPollId in getblocktemplate

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, an attacker authenticated to an enabled Zebra RPC endpoint can terminate zebrad by supplying a getblocktemplate LongPollId containing multi-byte UTF-8 characters. In zebra-rpc/src/methods/types/longpoll.rs, LongPollId::fromstr...

glibc: glibc: Information disclosure or denial of service via ungetwc function with specific wide character encodings

A flaw was found in glibc GNU C Library. When the ungetwc function is called on a file stream using wide characters with specific overlapping single-byte and multi-byte encodings, it may attempt to read data outside of its allocated buffer. This can lead to the unintentional disclosure of sensiti...

HTTP Request Smuggling

Overview org.webjars.npm:hono is an Ultrafast web framework for the Edges Affected versions of this package are vulnerable to HTTP Request Smuggling via the app.mount function. An attacker can access unintended routes or resources by sending requests with percent-encoded multi-byte characters in...

CVE-2026-47676

Summary: In Hono, prior to 4.12.21, app.mount() strips the mount prefix from the raw URL pathname while route matching uses the percent-decoded path. This mismatch can cause the prefix to be stripped at the wrong position for percent-encoded multi-byte characters, causing the mounted sub-applicat...

CVE-2026-47676 Hono: app.mount() strips mount prefix using undecoded path, causing incorrect routing for percent-encoded paths

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.12.21, app.mount strips the mount prefix from the incoming request path using the raw URL pathname, while route matching is performed against the percent-decoded path. This inconsistency causes the...

USN-8174-1: XML::Parser vulnerabilities

It was discovered that XML::Parser incorrectly handled certain multi-byte UTF-8 characters. If a user or automated system were tricked into processing specially crafted XML data, a remote attacker could use this issue to cause XML::Parser to crash, resulting in a denial of service or to possibly...
