McDonald's
Breach
Rankiteo Explanation
Attack with significant impact with internal employee data leaks
Description: The burger chain McDonald was targeted by hackers in a cyber attack. The hackers infiltrated its systems and stole personal data of employees in South Korea and Taiwan. The breach even compromised business contact information for U.S. employees and franchisees and restaurant information.
McDonald's
Breach
Rankiteo Explanation
Attack with significant impact with customers data leaks
Description: One of the service providers McDonald hired in its Costa Rica branch left its client data exposed which resulted in a data breach incident. The hackers accessed client names, marital status, address, email, document identification numbers, and phone numbers from an unprotected database. McDonald’s has informed the local legal authorities and started the investigation.
McDonald's
Breach
Rankiteo Explanation
Attack with significant impact with customers data leaks
Description: McDonald's shares dropped by as much as 1.7% after equity analysis firm Redburn Atlantic downgraded its stock rating from buy to sell. The downgrade was due to the potential impact of GLP-1 drugs on eating habits, which could result in a loss of up to 28 million customer visits and a revenue loss of $482 million per year. The drugs, which suppress appetite and regulate blood sugar, are expected to significantly affect lower-income consumers, a key demographic for McDonald's. This change in consumer behavior, combined with inflationary pressures and pricing fatigue, poses a significant threat to the company's earnings.
McDonald's
Breach
Rankiteo Explanation
Attack with significant impact with customers data leaks
Description: McDonald's Canada has acknowledged that hackers have taken approximately 95,000 job seekers' personal information from its hiring website. The names, addresses, emails, phone numbers, employment histories, and other personal information of job hopefuls were exposed in a data breach; the corporation has opened an inquiry into this incident. Approximately 95,000 restaurant job applicants' personal information has been leaked as a result. Those who applied online for a job at a McDonald's Canada restaurant are the ones who are affected. Thankfully, McDonald's Canada does not request sensitive data like social security numbers, health information, or financial information, so the recruitment website has been shut down.
McDonald's
Breach
Rankiteo Explanation
Attack threatening the economy of a geographical region
Description: The burger chain McDonald's Canada suffered from a data breach incident that leaked 95,000 job seekers information. The information includes the names, addresses, email addresses, phone numbers, and employment backgrounds of candidates who applied online for a job at McDonald’s Canada between March 2014 and March 2017. After learning of the attack, McDonald's pulled down the website, and the corporation affirmed that it will be shut until the investigation is over.
McDonald's
Vulnerability
Rankiteo Explanation
Attack with significant impact with customers data leaks
Description: A vulnerability in McHire, the AI-powered recruitment platform used by a vast majority of McDonald’s franchisees, exposed the personal information of over 64 million job applicants. The vulnerability allowed unauthorised access to sensitive data, including names, email addresses, phone numbers, and home addresses. The issue was due to an Insecure Direct Object Reference (IDOR) on an internal API and weak default credentials. The incident was swiftly addressed by Paradox.ai and McDonald's, but it highlighted the risks associated with rushing AI deployments without proper security measures.
McDonald’s
Vulnerability
Rankiteo Explanation
Attack with significant impact with customers data leaks
Description: A series of critical vulnerabilities in McDonald’s digital infrastructure exposed severe security lapses across multiple systems. The flaws began with a client-side validation bug in the mobile app, allowing free food exploits, but escalated to far graver issues. The **Design Hub**, used by teams in 120 countries, relied on a client-side password and had an open registration endpoint, enabling unauthorized access to confidential brand assets. Plaintext password emails, exposed **Magicbell API keys**, and listable **Algolia search indexes** leaked employee and user data, including names, emails, and access requests.Employee portals were equally compromised: low-level staff could access the **TRT corporate tool** to search global employee details (including executives’ emails) and exploit an **impersonation feature**. The **Global Restaurant Standards (GRS) panel** lacked authentication, allowing API-based HTML injection, while misconfigured **Stravito access** exposed internal documents. A separate vulnerability in McDonald’s **AI-powered hiring system** exposed **64 million job applicants’ personal data** due to weak security (password: '123456'). Though most issues were patched post-disclosure, some endpoints remained accessible, and a collaborator was terminated over 'security concerns.' The incident highlights systemic failures in authentication, access control, and secure coding practices, with no bug bounty program or reliable reporting mechanism in place.

Description
FreePBX Endpoint Manager is a module for managing telephony endpoints in FreePBX systems. Versions prior to 16.0.96 and 17.0.1 through 17.0.9 have a weak default password. By default, this is a 6 digit numeric value which can be brute forced. (This is the app_password parameter). Depending on local configuration, this password could be the extension, voicemail, user manager, DPMA or EPM phone admin password. This issue is fixed in versions 16.0.96 and 17.0.10.

Description
Neuron is a PHP framework for creating and orchestrating AI Agents. In versions 2.8.11 and below, the MySQLWriteTool executes arbitrary SQL provided by the caller using PDO::prepare() + execute() without semantic restrictions. This is consistent with the name (“write tool”), but in an LLM/agent context it becomes a high-risk capability: prompt injection or indirect prompt manipulation can cause execution of destructive queries such as DROP TABLE, TRUNCATE, DELETE, ALTER, or privilege-related statements (subject to DB permissions). Deployments that expose an agent with MySQLWriteTool enabled to untrusted input and/or run the tool with a DB user that has broad privileges are impacted. This issue is fixed in version 2.8.12.

Description
Neuron is a PHP framework for creating and orchestrating AI Agents. Versions 2.8.11 and below use MySQLSelectTool, which is vulnerable to Read-Only Bypass. MySQLSelectTool is intended to be a read-only SQL tool (e.g., for LLM agent querying, however, validation based on the first keyword (e.g., SELECT) and a forbidden-keyword list does not block file-writing constructs such as INTO OUTFILE / INTO DUMPFILE. As a result, an attacker who can influence the tool input (e.g., via prompt injection through a public agent endpoint) may write arbitrary files to the DB server if the MySQL/MariaDB account has the FILE privilege and server configuration permits writes to a useful location (e.g., a web-accessible directory). This issue is fixed in version 2.8.12.
