Newly released CVEs across every platform — sleek to read, verbose on demand, and served raw as markdown for AI and agent ingestion. Severity reads as depth: the deeper the contact, the graver the threat.
Depth = severity + exploitation
CVE-2026-100702Medium· 5.9Nodemailer before 10.0.2 fails to properly flatten deeply nested arrays in recipient fields such as to, cc, and bcc, allowing attackers to cause stack exhaustion. Attackers can supply a deeply nested JSON recipient array that triggers re…
CVE-2026-100701Medium· 5.9Nodemailer versions 5.0.0 through 10.0.1 use a process-global DNS cache that is keyed only by the DNS host, while each cache entry also stores the caller-specific TLS servername. When two direct TLS/SMTPS transports (secure: true) resolv…
CVE-2026-100699Medium· 5.3Nodemailer is a Node.js email-sending library. In versions >= 9.1.0 and < 10.0.9, the address parser (src/addressparser) mishandles addresses whose local-part is a quoted string and that are followed by RFC 5322 comments, allowing traili…
CVE-2026-100700High· 7.5nodemailer before 10.0.6 contains a denial of service vulnerability in the addressparser free-text fallback regex pattern that exhibits quadratic backtracking behavior. Attackers can supply crafted email header values with long whitespac…
CVE-2026-92595Medium· 5.9PoCNodemailer (npm package `nodemailer`) versions 9.1.0 and earlier do not honor the `disableFileAccess` and `disableUrlAccess` sandbox options when message content is resolved through the public plugin API `MailMessage.resolveContent()` us…
CVE-2026-92597Medium· 6.5Nodemailer versions >= 6.9.16 and < 9.1.0 mis-parse RFC 5322 comments in email addresses: in lib/addressparser, a comment closed immediately before a non-break character causes the tokenizer to concatenate the atoms surrounding the comme…
CVE-2026-92598Medium· 6.5PoCNodemailer before 9.1.0 fails to apply UTS-46 normalization when encoding international domain names, causing the domain resolver to compute a different Punycode A-label than standards-compliant parsers. Attackers can craft recipient add…
CVE-2026-92596High· 7.5PoCNodemailer before 9.1.0 contains a quadratic time complexity vulnerability in the addressparser component that allows remote attackers to cause denial of service by supplying a crafted comma-separated address list. Attackers can send a s…
CVE-2026-90776High· 7.5PoCNodemailer versions 9.1.0 through 10.0.4 contain a quadratic time complexity vulnerability in the addressparser component when parsing email addresses with RFC 5322 comments. Attackers can craft malicious email headers with comment-separ…
GHSA-8m3c-c648-2xjjMedium· 5.9Nodemailer: resolveContent() on a MailMessage bypasses disableFileAccess/disableUrlAccess when called with the legacy signature
GHSA-wmmp-3585-3rmpMedium· 6.5Nodemailer: IDN/Punycode domain allow-list bypass leads to email delivery to an attacker-controlled domain
GHSA-cc9r-2j5m-2m83Medium· 6.5Nodemailer: Recipient-domain validation bypass via RFC 5322 comment mis-parsing leads to email delivery to an attacker-controlled domain
GHSA-2x7j-588g-ccc2High· 7.5Nodemailer: Quadratic (O(n²)) time complexity in addressparser allows remote denial of service via a crafted address list
CVE-2026-82662Medium· 6.5PoCNodemailer before 8.0.8 disables TLS certificate verification in lib/fetch/index.js through rejectUnauthorized: false, allowing attackers to intercept OAuth2 token requests. Attackers in a machine-in-the-middle position can capture OAuth…
CVE-2026-82661Medium· 5.4PoCNodemailer before 8.0.9 fails to sanitize carriage return and line feed characters in list comment fields, allowing attackers to inject arbitrary message headers. An attacker with control over list.*.comment parameters can inject CRLF se…
GHSA-p6gq-j5cr-w38fHigh· 7.1Nodemailer: Message-level raw option bypasses disableFileAccess/disableUrlAccess, enabling arbitrary file read and full-response SSRF in the delivered message
GHSA-r7g4-qg5f-qqm2Medium· 6.5Nodemailer: Improper TLS Certificate Validation in OAuth2 Token Fetch Enables Credential Interception
GHSA-wqvq-jvpq-h66fMedium· 5.4Nodemailer jsonTransport bypasses disableFileAccess and disableUrlAccess during message normalization
GHSA-268h-hp4c-crq3Medium· 5.4Nodemailer: CRLF injection in Nodemailer List-* header comments allows arbitrary message header injection
A summary of everything that shipped over the last two weeks — the whole corpus is open, agents get change feeds, alias resolution and EPSS movers, and the data now includes CVE.org, vendor CSAF, aggregated exploits and per-source scores.
A step-by-step guide to plugging VulnSea into automated and agentic workflows — poll the delta, triage without burning tokens, match an SBOM, and let an MCP-native model do the reasoning.
