CVE-2026-16270: Inefficient Regular Expression Complexity

Open Mercato does not validate regex rules. An attacker with privileges to create the regex rule can add an unsafe regex to a field. When someone provide the proper string it can result in a DoS attack. This issue was fixed in version 0.6.4...

Gitea: Unauthenticated ReDoS via CODEOWNERS pattern matching allows denial of service

This issue has been found by a security agent and review by myself. Gitea's CODEOWNERS feature uses the regexp2 library to match file paths against ownership rules. User-supplied patterns are passed directly to regexp2.Compile with no sanitisation and no match timeout. This allows an attacker to...

linkify-it: Quadratic-complexity DoS via the `mailto:` validator scan-loop on attacker text

Summary linkify-it's schema-scan loop .test / .match, the documented public API invokes the mailto: schema validator at every mailto: occurrence in the input text. For each occurrence the validator does text.slicepos an On copy and runs an email regex whose local-part class srcemailname greedily...

SUSE CVE-2026-14741

HTTP::Date versions before 6.08 for Perl allow CPU exhaustion via polynomial regex backtracking in parsedate. parsedate matches the date string against a chain of alternative regexes, and str2time delegates to it. Several of these patterns place unbounded quantifiers next to each other before a...

CVE-2026-55470

A flaw was found in HAPI FHIR, a Java implementation of the HL7 FHIR standard. The fix for a previous vulnerability CVE-2026-45367 was incomplete in the DSTU2 module. Specifically, the FHIRPathEngine.matches function in org.hl7.fhir.dstu2 did not include protection against regular expression...

rabbitmq-server: RabbitMQ: Authorization bypass via regular expression injection in MQTT client ID

A flaw was found in RabbitMQ. An authenticated MQTT Message Queuing Telemetry Transport user can bypass topic-level authorization by injecting regular expression operators. This occurs because the client ID, provided by the user in the MQTT CONNECT packet, is inserted into authorization regex...

@astrojs/netlify generates an overly-broad Netlify Image CDN allowlist because remotePatterns.pathname metacharacters are not escaped

Summary The @astrojs/netlify adapter converts each image.remotePatterns entry into a regular expression that is written to .netlify/v1/config.json under images.remoteimages. Netlify's Image CDN uses these regexes as the allowlist that decides which remote image URLs it will optimize...
