WordPress fixed Comment2Shell in 25 releases on one day; check yours is one of them, and that no plugin arrived first

WordPress core shipped 25 security releases on 17 September for a comment XSS that can reach an administrator's session. What to confirm, which wp-config setting actually blocks plugin upload, and why updating does not remove a plugin already added.

A stolen Ribon app key pulled BigCommerce shopper data in one evening, then stayed live almost four days

The Ribon breach on BigCommerce: what each party has said, why app tokens cannot be revoked by merchants, the hours lost at each step, and why the app is not BigCommerce's sub-processor under UK GDPR.

One in 225 Anthropic-credited CVEs is confirmed exploited, and that number proves less than it seems

225 Anthropic-credited CVEs, none in CISA KEV and one in VulnCheck KEV. We recounted the data: the low rate is normal, the sample is young, and UK teams should prioritise by KEV and EPSS, not by who found the bug.

British Columbia sues OpenAI over Tumbler Ridge on a duty to warn police that no court has yet tested

British Columbia's complaint against OpenAI repeats, heading for heading, the eight claims the victims' families filed in April, and rests on California common law rather than a provincial statute. What it alleges, what OpenAI has said on the record, and what UK deployers should check.

Defender can report protected while its updates stall: how to prove signatures are current across an estate

BigDiskBuster, released on 19 to 20 September 2026, keeps Defender on whatever signatures it already has. Microsoft's own reports can call a device up to date for seven days. Here is how to measure currency, not status.

Only the Zyxel switch flaw is in CISA's KEV; the Veeam agent exploitation claim rests on one vendor headline

CVE-2026-7273 in Zyxel GS1900 switches entered KEV on 21 September with a 24 September deadline after GreyNoise documented data theft from 996 switches. CVE-2026-32996 in Veeam Agent for Windows has a public PoC but no KEV entry.

MPs invited four AI labs to answer ten safety questions that no UK law currently answers

Four identical letters, ten questions, seven days to confirm. What the committee's papers actually say, what it can and cannot compel, and where UK AI and cyber law really stand before the 13 October hearing.

Meta's Muse zero-day: one writable Mac setting hands local malware the agent's token and every linked device

An undocumented setting in Meta's Muse Mac app lets malware or one pasted command redirect dictation, inject instructions and steal the account token. What is verified, what Meta's Secure VM does and does not protect, and what UK teams should do.

Threat Intel22 Sept 2026

Talos's CLOSEDQUORUM lets four LLMs vote on an implant's next move, but the only public build is inert

CLOSEDQUORUM asks DeepSeek, Qwen, Mistral and Gemini which of four attack actions to take, then acts on the plurality. Talos found placeholder keys, no confirmed victims and a narrower first than the headline suggests.

AWS quarantines a leaked access key in 10 seconds, but the key keeps working for anything not on the deny list

AWS's AWSCompromisedKeyQuarantineV3 went on 10 seconds after a test leak. It is a deny list, not a lockdown: what it blocks, what it leaves open, and what you still have to do.

Heretic automates stripping refusals from open-weight models. Its headline score counts 33 words, not harm

Heretic's 97 to 3 refusal result counts 33 words in the first 100 tokens, not harm. The real finding is older: in-model safety is a default, not a control, and UK organisations need controls outside the weights.

Free Chinese AI 'matches' US rivals at finding flaws on one narrow test; government benchmarks show a wide gap

What the benchmarks behind the Chinese AI bug-finding headline actually measured, why the government tests disagree, and what UK organisations should weigh before running a Chinese open-weight model.
