We are pleased to announce the release of Vulnerability-Lookup 6.0.0! This release is centred on two themes. Notifications leave the e-mail-only world: a subscription can now push its reports to any HTTPS endpoint — a chat channel, a SIEM, a ticketing system — with a configurable payload, under a strict outbound policy. And the local exploit hazard model moves from an experiment to a first-class citizen of the platform: two new API endpoints, hazard-ordered reports, per-subscription parameters and daily standing exposure alerts. On top of that: a vulnerability credits index with rankings and search, SSVC v2.0 decisions on the CVE page, an import_dump command to bootstrap an instance from the public dumps, and a batch of security fixes.

Vulnerability-Lookup (https://github.com/...) is an open-source platform (AGPL) for fast vulnerability lookup and correlation across many sources — CVE, EUVD, GHSA, OSV, CSAF/VEX, national CERTs — with collaborative annotation, sightings and coordinated disclosure. 6.0.0 is out today; two big additions this round.

Webhook notifications

Product notifications are no longer e-mail only. A subscription can push its reports to any HTTPS endpoint — a chat channel, a SIEM, a ticketing system — instead of, or in addition to, e-mail. HTTP method, custom headers and a payload template are all configurable, so the same mechanism feeds a generic JSON collector or the specific shape Mattermost/Teams/DingTalk/Telegram expect.

Targets are held to a strict outbound policy, enforced when the form is saved and again at delivery time: HTTPS on a standard port, no redirects, delivery pinned to the validated IP, private/loopback/link-local refused (IPv6 transition addresses judged by their embedded IPv4 destination), URL-shortener and dynamic-DNS domains rejected via the MISP warning lists, and URL paths redacted from failure logs.

Local exploit hazard

An implementation of the model from arXiv:2607.24618 (https://arxiv.org/abs/2607.24618), which turns an EPSS forecast into an exploitation risk estimate that accounts for your environment — compensating controls (globally or per attack vector), KEV policy weighting, and exponential or KEV-calibrated Weibull age decay.

POST /api/exploit-hazard — a single vulnerability instance, resolved from a vulnerability id or from explicit values.
POST /api/exploit-hazard/batch — aggregates a whole exposed set into the aggregate daily hazard, the expected number of exploitation events over the horizon, and the Poisson probability of at least one event.

The same model drives the notifications: reports are ordered by individual hazard and annotated with EPSS score, age and horizon probability. Each subscription can localize the estimates with its own parameters, and a daily standing exposure evaluation alerts on upward threshold crossings, listing the vulnerabilities whose remediation would lower the exposure most.

Also in this release

A vulnerability credits index — credited researchers from CVE 5, OSSF and CSAF records, indexed and ranked at /credits/ with search and pivots from every advisory
SSVC v2.0 decisions on the CVE page, extracted from every container (CNA and ADPs), normalized and attributed
import_dump — bootstrap a fresh instance from the public NDJSON dumps (a one-time bootstrap, not a sync mechanism)
EUVD: KEV catalog linking and a score-ordered EPSS index
Security fixes: XSS in tag rendering, SSE stream gated on confirmed accounts, single-use activation/recovery tokens, outbound-URL policy on remote sync, and authenticated responses kept out of shared caches
Project governance, maintainer list, roadmap and privacy documentation
