GHSA-H35F-9H28-MQ5C setuptools: MANIFEST.in exclusion bypass in sdist via Unicode normalization collision (NFC/NFD) on macOS APFS/HFS+

Summary When building a source distribution python -m build --sdist / setup.py sdist, setuptools' FileList applies MANIFEST.in directives exclude, global-exclude, recursive-exclude, prune by matching a compiled glob against on-disk file names byte-for-byte, with no Unicode normalization. On...

fast-uri vulnerable to host confusion via failed IDN canonicalization

Impact fast-uri versions = 2.3.1, = 4.0.0 fail to canonicalize Unicode/IDN hostnames for HTTP-family URLs. The IDN conversion path calls URL.domainToASCII... on the global WHATWG URL constructor, where that helper does not exist. The resulting TypeError is silently routed into parsed.error, but...

golang.org/x/net/idna: golang: net/http: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing

A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname for example, xn--example-.com returns example.com instead of an error. Applications that validate the ASCII form then convert to Unicode may grant acce...

nodejs: Node.js: Authentication bypass due to TLS hostname handling and unicode dot separator mismatch

A flaw was found in Node.js. This flaw involves a mismatch in how Node.js handles TLS Transport Layer Security hostnames and unicode dot separators during authentication. This mismatch can lead to a wildcard-depth authentication bypass. An attacker could exploit this to bypass intended security...

perl-XML-LibXML: XML::LibXML: Denial of Service via truncated UTF-8 in XML node names

A flaw was found in XML::LibXML for Perl. A remote attacker could exploit this vulnerability when processing specially crafted XML node names containing incomplete UTF-8 character sequences. This can lead to an out-of-bounds read in heap memory, potentially causing the application to crash and...

Security Bulletin: IBM i is Affected By Multiple Vulnerabilities in OpenSSL

Summary OpenSSL for IBM i is vulnerable to out-of-bounds read when parsing a crafted DER-encoded ASN.1 structure with a 2 gigabyte primitive element or when using Cryptographic Message Services CMS password-based decryption and processing a stream-mode KEK cipher CVE-2026-34180, CVE-2026-9076,...

CVE-2026-48760

Symfony HtmlSanitizer/UrlSanitizer::parse() had an underinclusive denial for BiDi formatting characters and Unicode whitespace, allowing percent-encoded BiDi marks to bypass the check. The issue affects UrlSanitizer::parse() behavior from Symfony 6.1.0 up to 6.4.41, 7.4.13, and 8.0.13, where raw ...

CVE-2026-48760 Symfony: HtmlSanitizer URL Parser Deny Gates Underinclusive: Percent-Encoded BiDi Marks and Unicode Whitespace Bypass Visual-Spoofing Defense

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. From 6.1.0 until 6.4.41, 7.4.13, and 8.0.13, UrlSanitizer::parse rejected raw BiDi formatting characters but not percent-encoded forms and used an ASCII-only whitespace check, allowing sanitized URLs...

CVE-2026-48758

A flaw was found in the @sigstore/core component. The preAuthEncoding function incorrectly uses Node.js 'ascii' encoding when converting Pre-Authentication Encoding PAE strings to bytes. This encoding truncates Unicode characters to their low byte, allowing an attacker to substitute characters in...
