Chrome 155 Is Out: Why Your Office PCs May Still Be Running the Old Version

Chrome 155 security update for office PCs

On 13 October 2026 Google pushed Chrome 155 to the Stable channel with 37 security fixes, and seven of them are rated critical. Google has not said any of them are being used in attacks yet. Still, the browser is where staff open email links, portals and PDFs, so an office that has not fully updated is carrying avoidable risk.

The version number to look for

  • Windows and Mac: 155.0.8059.79 or .80
  • Linux and Android: 155.0.8059.79
  • Anything lower should be flagged for an update

Where updates usually get stuck

  • The update downloads, but nobody restarts the browser
  • Staff keep dozens of tabs open for weeks, so the old build keeps running
  • Counter, kiosk and meeting-room PCs are simply forgotten
  • Edge and other Chromium browsers get their own separate fixes, so they need their own check

The fix is simple: list versions across all devices, force a relaunch, cover the forgotten machines, update Android phones through Google Play, and add browser updates to your monthly patch cycle.

Self-Hosted GitLab? CVE-2026-97229 Is Being Exploited, Check Your Version

Image
If your team runs its own GitLab server, this one needs attention this week. CVE-2026-97229 is a CVSS 10.0 integer overflow in the regular expression compiler used by GitLab CI/CD. A crafted regex in a CI/CD configuration can let an attacker run code on the server. GitLab shipped fixes on 12 October 2026, and CISA added the flaw to its Known Exploited Vulnerabilities catalogue on 29 October 2026. Which versions are affected 19.2 branch: fixed in 19.2.8 19.3 branch: fixed in 19.3.5 19.4 branch: fixed in 19.4.2 GitLab.com and GitLab Dedicated are already patched The root cause sits in Onigmo, the regex engine inside Ruby, so source or custom builds with their own Ruby may need a separate Ruby update. A short action list List every self-managed GitLab instance, including test and forgotten ones Upgrade each one to the fixed version for its branch Turn off open sign-up and limit who can push to public projects until patched Review recent .gitlab-ci.yml changes, unknown users and o...

Hiring a Website Developer? Six Warning Signs to Spot Before You Sign

Image
Many business websites get built twice. The first vendor wins on price, and a few months later the site is slow on mobile, the contact form stops working, and nobody can reach the developer. Most of this can be avoided with the right questions before signing. Warning signs in a website quote A fixed price given before anyone asks about content, integrations or users No live examples, or examples that no longer load Reluctance to register the domain and hosting in your company's name No mention of testing, backups or updates Pressure to sign fast with a "this month only" discount A launch plan with no redirects for old URLs, which can wipe out search traffic What to ask for instead An itemised proposal: pages, templates, features, integrations, revisions, testing, hosting and support A meeting with the project manager and lead developer, not only sales Written ownership of domain, hosting, source code, design files and content A short paid discovery phase that p...

Laravel Projects That Need a Rebuild After 18 Months: Five Causes and How to Avoid Them

Image
A common story: a business picks a Laravel vendor for a low quote, and about eighteen months later the app is slow, small changes break other features, and the next vendor says it must be rebuilt. Laravel is rarely the problem. The way the vendor was chosen usually is. Five causes behind costly rebuilds Business rules stuffed into controllers, so a new GST field touches many files No automated tests, even though Laravel supports PHPUnit and Pest The N+1 query problem: a list of 100 orders running 101 queries Security left to chance: debug mode on in production, or secrets stored in the code repository The vendor, not the client, holding the repository, servers and domain Version support matters too Per the official Laravel documentation, each major release gets bug fixes for 18 months and security fixes for 2 years. Laravel 13 came out in March 2026, and security support for Laravel 12 runs until February 2027. Plan upgrades in your maintenance contract. Before you sign Have an ...
