CVE-2026-77680 Libsoup3: libsoup: quadratic cpu denial of service in http range coalescing after cve-2025-32907 fix

An algorithmic complexity flaw exists in libsoup's HTTP Range header processing that persists after the CVE-2025-32907 fix. CVE-2025-32907 addressed memory amplification when a client repeated the same range many times in a single Range header. Commit 9bb92f7a corrected merge correctness in...

CVE-2026-77680

libsoup contains an algorithmic complexity flaw in its HTTP Range header processing that persists after the CVE-2025-32907 fix. The root cause is that the coalescing loop in soup_message_headers_get_ranges_internal() uses g_array_remove_index() for each merged range, resulting in O(N²) work when ...

CVE-2026-55620

emlparser serves as a python module for parsing eml files and returning various information found in the e-mail as well as computed information. Prior to 3.0.2, emlparser.routing.noparenthesis in emlparser/routing.py removes parenthesized CFWS comments from Received: headers with a regex-based...

eml_parser vulnerable to DoS via deeply nested parens in Received headers

Summary emlparser strips parenthesised CFWS comments from Received: headers using a regex-based fix-point loop. The loop has quadratic time complexity in the number of nested parens. A single Received: header containing 5,000 nested parens causes 1.3 seconds of CPU saturation per parsed message;...

CVE-2026-55620

eml_parser is a Python module for parsing EML files. Prior to 3.0.2 , the eml_parser.routing.noparenthesis function in eml_parser/routing.py removes parenthesized CFWS comments from Received: headers using a regex-based fix-point loop with quadratic running time in nesting depth. A single Receive...

CVE-2026-79658

Ech0 versions before 5.0.1 are vulnerable to a denial-of-service attack via the Accept-Language header. The i18n middleware, which runs on every HTTP request, passes the header unfiltered to golang.org/x/text/language.ParseAcceptLanguage. A gap in the CVE-2022-32149 mitigation caps - characters b...

CVE-2026-79658 Ech0 before 5.0.1 Denial of Service via Accept-Language

Ech0 before 5.0.1 does not impose any size or shape limit on the Accept-Language header processed by its i18n middleware, which runs on every HTTP request. The header is passed unfiltered to go-i18n's NewLocalizer, which internally calls golang.org/x/text/language.ParseAcceptLanguage. The...

Linux Distros Unpatched Vulnerability : CVE-2026-75140

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - jsoup through 1.23.2, fixed in commit 862ba2f, contains an uncontrolled resource consumption vulnerability in XmlTreeBuilder that allows remote attackers to...

net/mail: golang: net/mail: Denial of Service via pathological email address parsing

A flaw was found in the net/mail package within the Go standard library. A remote attacker could provide specially crafted, pathological email addresses. When these malformed email addresses are parsed by the consumePhrase function, it can lead to excessive resource consumption due to quadratic...

CVE-2026-75140

jsoup through 1.23.2, fixed in commit 862ba2f, contains an uncontrolled resource consumption vulnerability in XmlTreeBuilder that allows remote attackers to exhaust JVM heap memory by supplying a deeply nested XML document with uniquely-namespaced elements. The builder copies the entire inherited...

CVE-2026-58436

A flaw was found in Gitea. An unauthenticated remote attacker could exploit a quadratic-time algorithm in the ParseAcceptLanguage function, specifically within the Locale middleware. This vulnerability allows an attacker to send specially crafted requests, leading to excessive resource consumptio...
