E-commerce technology provider 91APP confirmed that one of its Commerce Cloud order databases was illegally accessed on October 3 via an unpatched third-party tool, Appsmith, after which the attacker retrieved database credentials from an internal GitLab instance [1]. On October 19, the Administration for Digital Industries (ADI), MODA conducted an on-site inspection confirming unauthorized data exfiltration, while the exact number of affected brands and individuals remains under verification [2]. Brands operating storefronts on 91APP should send anti-fraud alerts to members in accordance with 91APP's notifications, and consumers should not click links in emails that cite real order details [1][3].

Timeline
Technical details
What Happened
According to 91APP's incident statement, after receiving an initial customer report on October 4, its investigation confirmed on October 14 that one of the Commerce Cloud order databases had been illegally accessed on October 3; the root cause was an unpatched vulnerability in the third-party tool Appsmith, which allowed attackers to penetrate the internal network and obtain database credentials from an internal GitLab server [1]. 91APP also stated that it discovered traces of the autonomous AI penetration tool ARTEX within its systems [1].
Scope of Impact
On October 19, the Administration for Digital Industries (ADI), MODA, together with the National Institute of Cyber Security (NICS) and external experts, conducted an on-site inspection confirming that data had indeed been exfiltrated without authorization, though the specific personal data fields, number of individuals, and record counts remain under investigation [2]. The accessed data consisted of order information and did not include credit card details; Marketing Cloud, 91APP Payments, and iCHEF were unaffected [1]. Multiple listed companies using 91APP (including Munsin, Atunas, Kemao Biotechnology, Sea Mild, and Li Kang) subsequently issued material cybersecurity filings on MOPS, and consumers reported receiving emails impersonating merchants with real order details [3].
Response
91APP has removed Appsmith, rotated internal tokens and database credentials, restricted network connectivity between CI hosts and database segments, reported the breach to MODA under the Personal Data Protection Act on October 15, and proposed a consumer financial loss compensation and brand member communication plan [1]. ADI has initiated an administrative inspection requiring 91APP to inventory the exfiltrated data and notify affected brands and consumers .
Our analysis
The following is our opinion, not a sourced statement.
This is a textbook supply-chain cascade breach caused by a single point of failure at a third-party platform. Brands using any e-commerce platform or ERP should contractually require vendor notification timelines and patching SLAs; while brands cannot platform vulnerabilities themselves, they can shorten the time to notify members and reduce scam success rates.
Remediation
Vendor guidance
- 1Brands should verify whether they are on 91APP's affected list detect[1]
Inquire via the 91APP backend admin portal and notify affected members in accordance with legal requirements.
- 2
Our addition
- 1Enterprises should audit unpatched third-party tools verify[1]
Inventory internal low-code and admin tools (such as Appsmith) for version currency and external exposure, and segregate CI hosts from database network segments.
