Security researcher @weezerOSINT disclosed on April 20 that Lovable, the Swedish AI code-generation platform that just raised a $330M Series B at a $6.6B valuation, had a Broken Object Level Authorization flaw letting any free account read another user's project source code, hardcoded database credentials, AI chat transcripts, and customer data - using only five API calls. The /projects/{id}/* endpoints verified Firebase authentication but skipped any ownership check. On April 23 Lovable published a formal incident report admitting the exposure window ran February 3 to April 20, a full 76 days, caused by a backend regression that silently undid a fix shipped in 2025. Every Lovable project created before November 2025 was readable. The researcher demonstrated the impact by pulling source code from Connected Women in AI, a Danish nonprofit with over 3,700 edits in 2026 alone, extracting hardcoded Supabase credentials from that code, then querying the live database to retrieve real names, LinkedIn profiles, and Stripe customer IDs belonging to Accenture Denmark and Copenhagen Business School staff. Lovable's initial public response was to deny a breach occurred and blame its documentation and HackerOne triage partner before eventually apologizing.
Vercel updated its security bulletin on April 23 to disclose that ongoing forensics has uncovered additional customer accounts compromised in the Context.ai-linked breach that went public on April 19, and - more worryingly - a separate cluster of customer accounts with evidence of compromise that predates and appears unconnected to the Context.ai incident. CEO Guillermo Rauch confirmed on X that the threat actor has been active beyond Context.ai's compromise. Hudson Rock's forensic report traced patient-zero to a Context.ai employee whose laptop was infected by Lumma Stealer in February 2026 after downloading Roblox auto-farm scripts - a roughly four-week dwell time before the operator pivoted into Context.ai's AWS environment and then through OAuth tokens into Vercel's Google Workspace. The stolen credential set from that single laptop included Google Workspace logins, Supabase keys, Datadog tokens, Authkit credentials, and the support@context.ai account. Vercel has now confirmed non-sensitive environment variables in affected team scopes were readable to the attacker, and says customer notifications are going out individually rather than via a public list.
Rituals, the Amsterdam-headquartered cosmetics and home fragrance retailer with roughly 1,000 stores across Europe, the Middle East, and North America, disclosed on April 23 that attackers stole personal information from its 'My Rituals' membership database. The company has not yet said how many members were affected, only that 'personal information' was exfiltrated. No payment card data is reported to have been compromised. Rituals' membership program collects name, email, postal address, and purchase history to drive a loyalty and personalization program, so the exposed fields are ideal material for branded-lookalike phishing and physical-mail fraud referencing real past purchases. The company says it has informed Dutch data protection regulator Autoriteit Persoonsgegevens and is working with an external incident response firm. Rituals did not attribute the breach to a named group and has not described the initial access vector; the disclosure follows a wider April 2026 pattern in which loyalty and membership databases are repeatedly showing up as soft targets for extortion actors looking for PII-heavy datasets.
The Everest ransomware group listed Citizens Financial Group and Frost Bank on its leak site on April 20 with a six-day deadline that expires today. Everest claims 3.4 million Citizens records (names, addresses, account numbers) and 250,000 Frost records with the more sensitive set: SSNs, tax IDs, mortgage rates, and income data. Both banks confirmed the breach traces to a third-party vendor - a statement-printing provider for Citizens, a tax-document fulfillment firm for Frost - rather than direct compromise. Citizens disclosed publicly April 21; class-action lawsuits were filed April 23.
Follow-up: this is the origin-story update to the Vercel breach disclosed April 19 (which our publication did not cover at the time). Hudson Rock traced the initial compromise to a Context.ai employee whose laptop was infected by Lumma Stealer malware in February 2026 after the user downloaded Roblox 'auto-farm' scripts and game-exploit executors - a notorious delivery vector for infostealers. The malware harvested that employee's Google Workspace credentials plus access keys and logins for Supabase, Datadog, and Authkit. The haul also included the support@context.ai account, letting the attacker escalate inside Context.ai, reach its AWS environment, and then pivot through compromised Google Workspace OAuth tokens into a Vercel employee's enterprise workspace that had granted the 'AI Office Suite' app 'Allow All' permissions. The attacker (ShinyHunters, now selling the data for $2M on BreachForums) read Vercel environment variables not flagged as 'sensitive.' Google pulled the Context.ai Chrome extension (ID omddlmnhcofjbnbflmjginpjjblphbgk) on March 27 - it embedded an OAuth grant for read access to users' entire Google Drive. The lesson is brutal: one employee's personal risky behavior on a work device cascaded through four SaaS platforms into a supply-chain breach that a threat actor is now auctioning.
France Titres (Agence nationale des titres securises, ANTS), the French government agency responsible for issuing driver's licenses, national ID cards, passports, and immigration documents, has confirmed a security incident on the ants.gouv.fr portal. The agency detected the compromise on April 15 and published an acknowledgment April 20, saying individual and professional account data may have been exposed. On April 16, a threat actor using the alias 'breach3d' claimed responsibility on a hacker forum, alleging theft of up to 19 million records. The attacker says the stolen data contains full names, contact details, birth data, home addresses, account metadata, gender, and civil status. ANTS operates under the French Ministry of the Interior and is the authoritative source for official French identity documents, making any data leak a foundational risk for downstream phishing, social engineering, and identity fraud. The agency has notified France's data protection authority (CNIL), the Paris Public Prosecutor, and national cybersecurity agency ANSSI. ANTS is telling users no action is required but to exercise 'extreme caution' with any SMS, phone calls, or emails claiming to come from the agency - the stolen data is ideal raw material for targeted impersonation scams.
Backfill from April 21: Anthropic confirmed an unauthorized Discord group quietly accessed Mythos - the company's most powerful AI cybersecurity tool, restricted to about 40 vetted partners including Apple, Microsoft, and Google. The group got in on the same day Mythos was announced (April 7) by piggybacking on a member who works at one of Anthropic's third-party contractors, then guessed the model's URL based on naming patterns from previously leaked information. Anthropic says the group used Mythos to build websites, not for attacks - but they had quiet access for two weeks. Mozilla used Mythos to find and patch 271 Firefox bugs.
On April 20 a threat actor using the alias 'dylanmarly' posted 12.6 GB of stolen data from Mexican cybersecurity firm BePrime, claiming compromise of admin accounts that had no MFA enabled. The dump includes plaintext credentials, financial transaction records, security audit and pentest reports detailing client vulnerabilities, plus API keys for 1,858 Cisco Meraki network devices and live surveillance camera feeds. Affected clients include Iberdrola (Spanish energy giant), ArcelorMittal, Whirlpool, and Alsea (Latin American operator of Starbucks, Domino's, Vips). BePrime then announced legal action against journalists reporting on it.
Cloud development platform Vercel disclosed a security incident on April 19 after a threat actor claiming to be ShinyHunters posted stolen data for sale on a hacking forum. Vercel CEO Guillermo Rauch confirmed the initial access came through a breach at Context.ai, an enterprise AI platform one Vercel employee had signed up for using their Vercel enterprise account with 'Allow All' OAuth permissions. Attackers compromised Context.ai, stole the OAuth token, took over the employee's Google Workspace account, and pivoted into Vercel environments. Once inside, they accessed environment variables not marked as 'sensitive' - these are stored unencrypted at rest, unlike sensitive env vars which Vercel encrypts. The attacker posted 580 employee records (names, emails, account status, activity timestamps) as a teaser, plus screenshots of an internal Vercel Enterprise dashboard. They claim to also have access keys, source code, database data, and API keys, though Vercel characterizes impact as a 'limited subset' of customers. Mandiant is engaged. This is the cleanest real-world example to date of the AI supply chain risk pattern everyone has been warning about: a third-party AI tool with broad OAuth scopes becomes the initial access vector into your primary infrastructure.
Booking.com has confirmed unauthorized access to its systems that exposed guest reservation data including names, email addresses, phone numbers, postal addresses, booking details, and any messages shared with accommodation providers. The company began emailing affected customers over the weekend but did not send alerts via the Booking.com app, creating confusion about whether the notification emails were legitimate. Booking.com says financial data was not accessed. The company has reset PIN numbers for affected reservations. The number of impacted users has not been disclosed, though Booking.com lists 6.8 billion bookings since 2010 across 30+ million properties. Reddit users are already reporting scam messages from people who appear to have real reservation details, suggesting attackers are using the stolen data for targeted phishing. The Register notes this follows a similar 2021 breach pattern where attackers compromised hotel staff logins to access the platform.
