CVE-2026-49477 Soup Sieve: Regular Expression Denial of Service (ReDoS) in soupsieve Selector Parser

Soup Sieve is a CSS selector library designed to be used with Beautiful Soup 4. Prior to 2.8.4, the CSS selector parser in soupsieve contains a regular expression vulnerable to catastrophic backtracking when processing an attribute selector with an unterminated quoted value in...

GHSA-MQXV-9RM6-W8QC Ech0: ParseAcceptLanguage `_` separator bypass enables ~70x CPU amplification via Accept-Language header in i18n.Middleware

Summary Ech0's i18n middleware runs on every HTTP request and constructs a fresh goi18n.Localizer from the raw Accept-Language header without imposing any size or shape filter. goi18n.NewLocalizer calls golang.org/x/text/language.ParseAcceptLanguage on the value internally. The underlying parser...

CVE-2026-47736

Summary: CVE-2026-47736 affects the Puma Ruby/Rack web server when PROXY protocol v1 is enabled. In affected releases (5.5.0 up to 7.2.1 and 8.0.2), Puma reads incoming bytes into an internal buffer while waiting for CRLF to detect a PROXY v1 line, allowing an attacker to send data without CRLF a...

Inefficient Algorithmic Complexity

Overview Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity via the decode process. An attacker can cause excessive CPU consumption and disrupt service availability by submitting specially crafted ASN.1 data containing OBJECT IDENTIFIER or RELATIVE-OID values...

PYSEC-2026-3457

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the univ.Real type converted its mantissa, base, and exponent value to a Python float using exact big-integer exponentiation. A BER, CER, or DER encoded REAL value only a few bytes long can carry a very large exponent, causing float...

CVE-2026-59886

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the univ.Real type converted its mantissa, base, and exponent value to a Python float using exact big-integer exponentiation. A BER, CER, or DER encoded REAL value only a few bytes long can carry a very large exponent, causing float...

PYSEC-2026-3455

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the BER decoder shared by the CER and DER codecs parses long-form tags by accumulating continuation octets without an upper bound on the tag ID size, allowing a crafted input to force construction of an arbitrarily large integer with C...

UBUNTU-CVE-2026-59884

CVE-2026-59886

Summary: pyasn1 before 0.6.4 contains a vulnerability in the univ.Real ASN.1 type where mantissa/base/exponent are converted to a Python float via exact big-integer exponentiation. This can cause excessive CPU/memory usage when decoding untrusted ASN.1 data and subsequently printing, logging, or ...

python: Python: CPU Denial of Service in HTML parser via repeated unterminated markup declarations

A flaw was found in Python. Its incremental HTML parser can be exploited by a remote attacker. By sending specially crafted, uncontrolled data with repeated, incomplete markup declarations, the attacker can cause the system to consume excessive central processing unit CPU resources. This leads to...

CVE-2026-53539

A flaw was found in Python-Multipart, a streaming multipart parser. A remote attacker can exploit this vulnerability by submitting a specially crafted application/x-www-form-urlencoded body. This can cause the QuerystringParser to perform inefficient processing, leading to excessive CPU...

CVE-2026-59869

A flaw was found in js-yaml, a JavaScript YAML parser and dumper. A remote attacker could exploit this vulnerability by providing a specially crafted YAML document containing a chain of mappings with merge keys. This could cause the parser to consume excessive CPU resources, leading to a Denial o...
