GitHub's cron scheduler creates this repository's scheduled runs four to
five hours late and drops the slots in between, so the hourly Hot CVEs
refresh cannot come from a cron. A workflow_dispatch call creates a run
within seconds, so a pacemaker workflow now sleeps until the next :05,
fires the refresh and its own successor, and keeps time by itself. Its
cron only restarts the chain if a link fails.
Hot CVEs loses its cron and the gate that was there to coexist with an
external trigger; nothing outside GitHub is involved any more.
GitHub's cron scheduler created the hourly run about five times a day,
four to five hours late. A systemd timer on the VPS now dispatches it every
hour. The cron stays as fallback and watchdog: a gate job skips it while
the trigger is alive, lets it run when the trending table is over 55
minutes old, and fails the run once it is over three hours old so the
failure email names the cause.
Also stage docs/kev.svg in every writer that redraws it, verify the index
in the link audit before committing like the other writers do, and refresh
the apt index before installing librsvg.
Commits pushed with the workflow token raise no push event, so site.yml
only ran on its 06:20 schedule and the site trailed the index by up to a
day. workflow_dispatch is exempt from that rule, so each writer now
triggers it after a successful push.
The push retry rebased onto the fetched main and, on a conflict, left HEAD
there; the next push then succeeded as a no-op and the run went green with
its changes discarded. Abort the rebase and fail instead.
The per-CVE pages read as a different site and disagreed with search about
their own contents. Both traced to the page generator having grown its own
copy of rules the browser already had.
Security:
- JSON-LD was serialised with json.dumps alone, which leaves < > and & raw. A
description containing "</script>" ended the element and turned the rest into
live markup. 78 descriptions in the corpus already carry that sequence; only
the 155-character meta trim kept them out of the payload. Escape to \u00XX.
Correctness:
- The PoC count summed only the repository column, so 19,940 pages announced
"0 public PoC exploits" directly above the ExploitDB and Metasploit entries
they were listing, in the title and meta description too. Count every source
the page renders, matching POC_FIELDS in logic.js.
- The severity chip took the highest score while search took the first, so
18,434 CVEs showed one severity in the results and another on the page. Both
now take the primary assessment, with the same Nuclei fallback search uses.
- Identical CVSS rows printed two and three times on 13,340 pages. Dedupe on
(version, score, vector) and label each survivor with its assessor from
row[4]; row[5] is the assessment type and left 129 pages showing two rows
both marked "Secondary".
- repo_from_url accepted any host containing "github" and kept .git suffixes,
so a clone URL and its plain form counted as two sources on the page and one
in search. 273 CVEs disagreed. Match repoFromUrl in logic.js exactly.
- 41 CVEs nobody has scored were unreachable by search, including by exact ID:
the severity filter tested membership of a list naming only the four scored
bands, so ALL excluded them. ALL now means all.
- EPSS percentiles printed a hard-coded "th": 51th, 62th, 93th on 21,100 pages.
- Search reported "1 PoCs", and the empty-results branch returned before
updating the live region, leaving it reading "loading index..." forever.
Deploy safety:
- A failed EPSS fetch returned {} and published it, silently erasing every
score from 82,000 pages. It now raises, as does a feed covering under 90%
of the index.
Presentation:
- CVE pages never loaded the webfonts the homepage loads, so all 82,468 fell
back to system fonts. This is why they looked unlike the rest of the site.
- 404.html referenced four CSS classes that no longer existed and rendered
unstyled, and its meta refresh threw a reader out of a search after two
seconds. It is now generated from the same constants and header as every
other page, and offers the search box instead.
- The homepage and the generated footer credited different sources. Both now
come from brand.SOURCES_LINE, and the build refuses to publish a homepage
that has drifted from it.
- Three aria-labels sat on div elements with no role, where they are ignored.
SEO:
- 61,936 pages filled "Related" with numerically adjacent CVEs, which are not
related to anything. Keep only shared-author relations; 20,532 pages have one.
- Sitemap lastmod described the CVE record, so a CVE that gained forty PoCs
still advertised a date from 2021. It now reflects the page, and each shard
carries its newest page's date rather than today's.
- TechArticle is not a type Google draws a rich result from, and its dates
claimed the CVE record's publication as the page's. Use WebPage with the
vulnerability as mainEntity.
- Curated sources and the CVE and NVD records no longer carry nofollow; the
crowd-sourced repository list still does.
The About box, the meta description, the og and twitter tags and the JSON-LD all
ended in a tacked-on list of features: "Updated hourly", "Free JSON API, no
signup", "Plain JSON, no key". None of it describes what the thing is, and the
meta description ran past where a result gets truncated anyway.
Four strings collapse to two so they cannot drift apart again. SUBTITLE is the
line under the wordmark and the social description; DESCRIPTION is the meta
description, the JSON-LD description and the GitHub About box. Both say what the
site is and stop.
82,000 CVEs sat behind one URL. Each of them is a query somebody types, and the
pages answering those queries belonged to other people: searching
"CVE-2026-72898 poc" returns SentinelOne, Horizon3, Wiz and BishopFox, all of
them serving one page per CVE.
Pages are flat files at /CVE-2026-72898. No /cve/ prefix, no extension, no
trailing slash. GitHub Pages resolves an extensionless request to the .html
beside it, checked against the live site rather than assumed.
Each page carries what the index already knows and nothing invented: every CVSS
assessment with its vector, EPSS with percentile, KEV date and ransomware flag,
Nuclei severity and CWE, and the PoC links grouped by source with stars and last
push. 94% of them carry three or more of those signals.
Discovery works two ways. sitemap.xml is now an index over one shard per year,
which fits the 50,000 URL cap on the split the data already has and lets a
crawler refetch only the year that moved. Search results link to the CVE page
instead of straight out to NVD, which moves to a chip beside CVE.ORG, and each
page links six related CVEs picked by shared PoC author.
Rendering all of them takes 20s and adds nothing to the repository: the payloads
they read are already gitignored and built in CI, so the pages go into the Pages
artifact and git never sees them.
The slug moved to 0xMarcio/pocindex, so the raw.githubusercontent URLs in the
README banner were riding a redirect. SLUG now lives in brand.py with the rest
of the identity and getTrending imports it.
The About description lost "with CVSS, KEV and EPSS. Free JSON API, no signup."
GitHub truncates listings near 150 characters, so that tail rarely rendered and
read as a feature list rather than a description. 142 characters now.
The MITRE disclaimer comes out of the footer. The brand carries no MITRE mark,
which was the reason for picking it, and referring to CVE identifiers by name is
ordinary descriptive use. NVD, Tenable and Rapid7 all do it without a notice.
_urltest.html is temporary and comes out in the next commit.
The site called itself three different things: CVE PoC Hub in the title, CVE
Radar in the h1 and the social metadata, and cve on GitHub. Google had no
consistent site name to settle on, so none of the mentions compounded. CVE
Radar was taken anyway, by SOCRadar's free tool and by cveradar.com.
Every user-facing name and URL now comes from scripts/brand.py, so the next
move is one edit rather than a sweep through the tree.
Also repairs the parts of the site a crawler could not use:
- robots.txt and sitemap.xml were both 404. scripts/build_seo.py writes them,
wired into the Pages job. trending_poc.json, kev.json and stats.json stay
crawlable because the first paint needs them; the five bulk payloads are
disallowed, which is 13.2 MB per crawl spent on data no crawler queries.
- Search state lives in ?q= now. Results were unlinkable, so nobody could cite
one and there was no route for a SearchAction to declare. replaceState
rather than pushState, so typing does not bury the back button.
- A WebSite JSON-LD block carries the name Google prints as the site name.
- The footer carries the MITRE trademark notice.
