CVE-2026-55099 icalendar: Algorithmic Complexity in Equality

icalendar is an RFC 5545 compatible parser and generator of iCalendar files for Python. From 7.1.0 until 7.1.3, the Component equality method in src/icalendar/cal/component.py compares nested subcomponents with two membership loops, and each membership test invokes the same method on child...

CVE-2026-55099

icalendar is an RFC 5545 iCalendar parser and generator for Python. In versions 7.1.0 through 7.1.3 , the Component equality method in src/icalendar/cal/component.py compares nested subcomponents using two membership loops that recursively invoke the same method on child components, producing O(2...

PT-2026-81851

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 soup...

linkify-it: linkify-it: Denial of Service via algorithmic complexity vulnerability

A flaw was found in linkify-it, a library for recognizing links with full Unicode support. The LinkifyIt.prototype.match function, the package's primary public API, has an algorithmic complexity of ON² for inputs containing many fuzzy links or emails. This can be exploited by a remote attacker...

CVE-2026-70453

A flaw was found in rsync. A remote attacker can exploit an algorithmic complexity vulnerability within the hashsearch function by sending a specially crafted file list. This can lead to the exhaustion of the receiver's CPU resources, causing a sustained denial of service DoS. Mitigation Disable...

BIT-ELASTICSEARCH-2026-72685 Inefficient Algorithmic Complexity in Elasticsearch Leading to Denial of Service

A flaw in Elasticsearch allows a low-privileged authenticated user who can index documents to submit a single small document containing a crafted user-supplied input. Processing one such document occupies a worker thread from a bounded pool for a disproportionate amount of time, degrading the...
