JW Marriott Global Score (TPRM)XXXX

Description: Marriott International Inc. faced a major data breach involving its Starwood-branded hotels, exposing the personal information of up to 383 million guests. The breach, which led to consolidated litigation, included sensitive customer data such as names, addresses, passport numbers, and payment details. The city of Chicago filed claims against Marriott, but the case was dismissed with prejudice after a settlement was reached. The incident underscores the severe consequences of large-scale data leaks, particularly in the hospitality sector, where trust and data security are critical. The breach not only risked financial fraud and identity theft for affected guests but also damaged Marriott’s reputation, leading to legal repercussions and regulatory scrutiny. The scale of the exposure affecting hundreds of millions highlights the systemic vulnerabilities in handling customer data across global operations.
Description: A third attack against the hotel chain, Marriott, has resulted in yet another data breach. This is the second time this year that data has been stolen from the hotel firm. An employee at the BWI Airport Marriott in Baltimore stated that about 20GB of data, including credit card numbers and PII of visitors and employees, had been stolen. The hacking organisation requested a ransom from Marriott to keep the data they had obtained from being released, but the money was not paid.
Description: Hotel giant Marriott International suffered a data breach after an unknown threat actor breached one of its properties and stole 20GB of files.

Description: Hotel giant Marriott International suffered a data breach after an unknown person gained access to information about certain Marriott associates by accessing the network of an outside vendor formerly used by Marriott.

Description: The California Office of the Attorney General disclosed a major data breach at Marriott International, Inc. on November 30, 2018, stemming from an unauthorized access to the Starwood guest reservation database. The breach, which began on or before September 10, 2018, exposed the records of approximately 500 million guests, with 327 million individuals having sensitive personal data compromised. This included names, mailing addresses, email addresses, and encrypted payment card numbers, though the encryption status of the latter was not confirmed to be broken. The incident originated from a vulnerability in Starwood’s systems, which Marriott had acquired in 2016, highlighting a failure in post-merger cybersecurity integration. The breach posed severe risks of identity theft, financial fraud, and reputational damage, given the scale and sensitivity of the exposed data. Regulatory investigations followed, with Marriott facing significant legal and financial repercussions, including fines under GDPR and other data protection laws. The incident underscored critical gaps in third-party risk management and the protection of customer data in large-scale corporate acquisitions.

SummaryA command injection vulnerability (CWE-78) has been found to exist in the `wrangler pages deploy` command. The issue occurs because the `--commit-hash` parameter is passed directly to a shell command without proper validation or sanitization, allowing an attacker with control of `--commit-hash` to execute arbitrary commands on the system running Wrangler. Root causeThe commitHash variable, derived from user input via the --commit-hash CLI argument, is interpolated directly into a shell command using template literals (e.g., execSync(`git show -s --format=%B ${commitHash}`)). Shell metacharacters are interpreted by the shell, enabling command execution. ImpactThis vulnerability is generally hard to exploit, as it requires --commit-hash to be attacker controlled. The vulnerability primarily affects CI/CD environments where `wrangler pages deploy` is used in automated pipelines and the --commit-hash parameter is populated from external, potentially untrusted sources. An attacker could exploit this to: * Run any shell command. * Exfiltrate environment variables. * Compromise the CI runner to install backdoors or modify build artifacts. Credits Disclosed responsibly by kny4hacker. Mitigation * Wrangler v4 users are requested to upgrade to Wrangler v4.59.1 or higher. * Wrangler v3 users are requested to upgrade to Wrangler v3.114.17 or higher. * Users on Wrangler v2 (EOL) should upgrade to a supported major version.
