Anna’s Archive Update - Threat Wire

Quick Overview

The weekly Threat Wire roundup covers a critical MongoDB exploit (CVE-2022-252547) that could allow unauthenticated heap memory reads, which was patched by MongoDB, and a security incident affecting Ubisoft's Rainbow Six Siege, where two separate groups exploited vulnerabilities to gain access to game currency and internal source code, respectively.

Key Points: A critical MongoDB exploit, CVE-2022-252547, allows unauthenticated heap memory reads via the ZLib compression protocol. The fix involves changing a line in messagecompressorzlib.cpp to return the actual length of decompressed data instead of allocated memory size. An incident affected Rainbow Six Siege, leading Ubisoft to intentionally shut down the game and its Marketplace on December 27, 2025. The first group exploited a Rainbow Six Siege service to ban players, modify inventory, and gift approximately $339.96 quadrillion worth of in-game currency. The second group, unrelated to the first, exploited a MongoDB instance using MongoBleed to pivot to an internal Git repository and exfiltrate source code dating back to the 1990s. Anna's Archive was confirmed to have scraped 86 million songs from Spotify using third-party user accounts, not by breaching Spotify's business systems, resulting in a CVSS score of 9.3. The host announced she is starting a new job the first full week of January 2026, meaning her schedule for Threat Wire might change.

Context: This video is a weekly cybersecurity news roundup called "Threat Wire," hosted by Allie Diamond. The episode covers several major security incidents occurring near the end of 2025, including a critical vulnerability in MongoDB, a significant breach affecting Ubisoft's Rainbow Six Siege, and an update regarding Anna's Archive scraping data from Spotify.

Detailed Analysis

The episode begins with a report on a critical MongoDB vulnerability, CVE-2022-252547, rated 8.7, which involves the ZLib compression protocol allowing unauthenticated heap memory reads. The fix, implemented in MongoDB versions 4.4.30, 5.0.27, 6.0.27, 7.0.28, and 4.4.30, corrects an issue in messagecompressorzlib.cpp where allocated memory size was returned instead of the actual decompressed data length. The second major topic concerns Ubisoft's Rainbow Six Siege, which was hit by an incident on December 27, 2025, causing the game and its Marketplace to be intentionally shut down. Two distinct groups were involved: the first group exploited a service to ban players, modify inventory, and gift an immense amount of in-game currency (estimated at $339,960,000,000,000,000 worth), which Ubisoft is rolling back. The second group exploited a MongoDB instance using MongoBleed to access Ubisoft's internal Git repository and exfiltrate source code from the 1990s onward. Finally, the host provides an update on Anna's Archive, confirming they scraped 86 million songs from Spotify using third-party user accounts, not by attacking Spotify's core business systems, which resulted in a CVSS score of 9.3 for the underlying vulnerability (CVE-2023-50144, affecting the LangChain core Python package). The host concludes by thanking viewers, mentioning her upcoming job change in January 2026, and promising to keep the weekly schedule consistent.
