Nodemailer: Process-global DNS cache reuses TLS `servername` across transports, enabling cross-tenant SMTP credential disclosure

Summary Nodemailer's process-global DNS cache is keyed only by host, but each cache entry also stores the caller-specific TLS servername. When two direct SMTPS transports use the same DNS host with different tls.servername values, the first transport's server name is returned to the second...

undici vulnerable to Denial of Service via unhandled error in WebSocket permessage-deflate decompression

Impact undici's WebSocket client including Node.js's bundled globalThis.WebSocket crashes the entire Node.js process when a remote WebSocket peer sends a permessage-deflate compressed message that crosses the decompressed-payload size limit and then contains a malformed DEFLATE block. In...

multer vulnerable to Denial of Service via orphaned disk writes on aborted uploads

Impact Multer's diskStorage can leave complete, orphaned files on disk when a multipart upload is aborted in the brief window before the storage engine assigns the file path. This is an incomplete fix of CVE-2026-5038: the earlier cleanup removes only in-flight uploads that already have a path, s...

morgan vulnerable to Log Injection via unescaped double quote in quoted log fields

Impact Morgan writes attacker-controlled request data to the access log. Its escaping added in 1.11.0 and 1.12.0 neutralizes control characters, the Unicode line separators, and backslash, but not the double quote 0x22, which is the field delimiter of the Apache combined log format morgan emits. ...

Angular SSR: Denial of Service (DoS) via Infinite Loop on Malformed DOCTYPE

fast-uri vulnerable to authority injection via an unvalidated port in serialize

Impact fast-uri serializes the port component of a URI without validating it. When recomposing the authority, fast-uri escapes the userinfo and host components but concatenates the port verbatim, so a port value that is not a sequence of digits can inject authority delimiters. For example,...

fast-uri vulnerable to host confusion via an unclosed bracket in the URI authority

Impact fast-uri accepts a host that contains an unbalanced or misplaced authority bracket or without reporting an error. A host that starts with but does not end with , such as @127.0.0.1, is neither validated as an IP literal nor canonicalized as a domain name, so parse returns it as the host wi...

ip-address: Address6.isLinkLocal() recognizes fe80::/64 rather than fe80::/10, allowing SSRF and trust-boundary bypass to on-link hosts

Summary Address6.isLinkLocal recognizes fe80::/64 rather than fe80::/10. Link-local unicast is the whole /10 under RFC 4291 §2.4 and the IANA IPv6 Special-Purpose Address Registry, so the method returns false for every link-local address outside the one /64 that stateless address autoconfiguratio...

ip-address: no classifier recognizes the NAT64 local-use range 64:ff9b:1::/48, allowing SSRF and trust-boundary bypass

Summary No classifier on Address6 recognizes the NAT64 local-use range 64:ff9b:1::/48 RFC 8215. isPrivate, isLoopback, isLinkLocal and their siblings all return false for every address in it, so an internal IPv4 destination written through a local-use NAT64 prefix 64:ff9b:1:7f00:0:100:: for...

jackson-databind: Duration XMLGregorianCalendar Unbounded Number Parse DoS

Summary jackson-databind 3.2.1 deserializes a JSON string bound to a javax.xml.datatype.Duration or javax.xml.datatype.XMLGregorianCalendar field by passing the raw string verbatim to DatatypeFactory.newDurationvalue / newXMLGregorianCalendarvalue. Per the XML-Schema lexical grammar these factory...

jackson-databind: Path Deserialization Missing Scheme Allowlist for FileSystemProvider Resolution

Summary A java.nio.file.Path field bound from untrusted JSON reaches JDKFromStringDeserializer.NioPathHelper.deserialize. The attacker string flows through new URIvalue → Path.ofuri, then on FileSystemNotFoundException into a ServiceLoader enumeration that calls provider.getPathuri on the first...

@grpc/grpc-js: The exact path match matcher incorrectly only applies a prefix match for case-insensitive matches

Impact When using RBAC to apply authentication rules, the exact path method name matcher applies a prefix match instead of an exact match for case-insensitive matches. As a result, if a service has a method with a name that is a prefix of the name of a different method, and they have different...
