CVE-2026-93751

A flaw was found in uri-js. This improper UTF-8 Unicode Transformation Format - 8-bit decoding vulnerability in the pctDecChars function allows a remote attacker to craft specially encoded payloads. These payloads can bypass platform decoder validation, leading to the injection of path traversal ...

golang.org/x/text: golang.org/x/text: Denial of Service via invalid UTF-8 input

A flaw was found in golang.org/x/text. The norm.Iter component can enter an infinite loop when processing input that contains invalid UTF-8 Unicode Transformation Format - 8-bit bytes. A remote attacker could exploit this vulnerability by providing specially crafted input, leading to a Denial of...

CVE-2026-87082

Net::IDN::Punycode versions before 2.590 for Perl hang, crash or return a wrong label via unvalidated malformed UTF-8 in encodepunycode.

CVE-2026-87082

The Net::IDN::Punycode Perl module (versions before 2.590 ) is vulnerable to a hang, crash, or incorrect label generation due to unvalidated malformed UTF-8 input in the encode_punycode function. The issue arises because neither backend validates well-formed UTF-8; specifically, on Perl 5.32+ , t...

pgadmin4-9.10-CVE-2025-13780

pgadmin4 9.11 元命令过滤器命令执行 摘要 pgAdmin 在修复 Issue 9320 时引入的 PLAIN 恢复元命令过滤器，在 SQL 文件以 UTF-8 字节顺序标记 EF BB BF 或其他特殊序列开头时无法检测到元命令。该实现的过滤器使用函数 hasmetacommands，该函数通过正则表达式扫描原始字节。该正则表达式未将这些字节视为可忽略，因此诸如 ! 的元命令仍未被检测到。当 pgAdmin 使用 --file 调用 psql 时，psql 会去除这些字节并执行命令。这可能导致在恢复操作过程中执行远程命令。 此绕过影响在提交...
