20-Year-Old PostgreSQL Flaw Gets Public PoC Exploit for Remote Code Execution

A proof-of-concept exploit for CVE-2026-2005 has been released, highlighting a significant vulnerability in the PostgreSQL pgcrypto extension that allows for remote code execution (RCE). This flaw, rooted in legacy code for nearly 20 years, enables attackers to escalate privileges and execute arbitrary commands on compromised servers. The vulnerability is found in the PGP session key parsing logic of the pgcrypto module and involves a heap-based buffer overflow, granting attackers arbitrary read and write access to memory. The exploit, shared by researcher “var77” on GitHub, demonstrates a multi-stage process that bypasses modern security measures like Address Space Layout Randomization (ASLR) using specially crafted PGP messages. The attack involves several steps, including heap pointer leakage, arbitrary memory read, identification of executable memory regions, and privilege escalation to the PostgreSQL superuser level, ultimately allowing the execution of OS-level commands. The vulnerability affects PostgreSQL deployments with the pgcrypto extension enabled, particularly those using vulnerable code versions. Successful exploitation can lead to full database compromise, unauthorized data access or modification, and potential lateral movement within networks. Organizations are advised to update PostgreSQL, restrict pgcrypto usage, limit user privileges, and monitor for unusual activity to mitigate risks.

Beware of Activating Them: 5 Android App Permissions That Pose a Threat to Your Data

Android applications often request various permissions upon installation, including access to the camera, microphone, contacts, messages, and accessibility features. Users frequently accept these requests without hesitation, which can compromise their device's privacy and security. Certain permissions, if granted to malicious apps, can enable monitoring of user activity, audio recording, location tracking, or unauthorized app installations. Five Android app permissions that require careful consideration before granting include: 1. Accessibility Services: Can allow untrusted apps to monitor screen content, read messages, track keystrokes, and perform actions on behalf of the user. 2. Display Over Other Apps: Allows apps to overlay content on other apps, which can be exploited by malicious apps to create deceptive interfaces. 3. Install Unknown Apps: Permits apps to install software from outside the Google Play Store, increasing the risk of malware. 4. Usage Data Access: Enables apps to monitor usage patterns, which can be used for targeted advertising or sold to data brokers. 5. Access to Contacts and Messages (SMS): Sensitive information can be intercepted by malicious apps, posing risks to account security. It is crucial to grant permissions that align with an app's intended function and to be cautious of unnecessary access.

5 Android App Permissions You Should Never Allow

Users should be cautious when granting permissions to applications on Android devices, as extensive access can lead to security vulnerabilities. Apps with accessibility permissions can perform actions like hacking passwords and altering device settings without user consent. Overlay permissions allow apps to display content over others, which can be exploited by malicious apps to trick users into providing sensitive information. Installing apps from unknown sources poses risks to device security and privacy. Usage data access enables apps to monitor user activity, which can be sold to advertisers. Granting access to contacts and SMS can lead to privacy concerns, as this information can be exploited by malicious entities. Users are advised to regularly review and manage app permissions to mitigate potential threats.

Another spyware maker caught distributing fake Android snooping apps

The Italian digital rights organization Osservatorio Nessuno has revealed a new malware called Morpheus, used by government agencies for surveillance. Morpheus is disguised as a phone updating application and can extract various data from targets' devices. The spyware is linked to IPS, an Italian firm specializing in lawful interception technologies, which claims to operate in over 20 countries. Morpheus is categorized as "low cost" due to its straightforward infection method, which involves tricking targets into installing the software. Authorities collaborated with the target's mobile service provider to obstruct data and send an SMS prompting the installation of the malware. Once installed, Morpheus exploits Android's accessibility features to access extensive information and masquerades as the WhatsApp application to solicit biometric data. The spyware's code contains Italian phrases and references to "Gomorra," indicating its connection to the Italian spyware industry. The attack is likely linked to political activism in Italy. IPS is among several Italian spyware manufacturers that have emerged following the decline of Hacking Team.

Take Control: Customer-Managed Keys for Lakebase Postgres

Encryption at rest is essential for cloud environments, especially in regulated sectors. Lakebase offers Customer Managed Keys (CMK), allowing organizations to control their encryption keys from preferred Key Management Services (KMS) like AWS KMS, Azure Key Vault, or Google Cloud KMS. Lakebase CMK manages both persistent storage and ephemeral compute, ensuring data security. Lakebase's architecture separates storage and compute layers, enabling elastic scaling and serverless operations. The storage layer maintains persistent data, while the compute layer consists of dynamic Postgres instances. This separation poses encryption challenges, addressed by Lakebase CMK through a hierarchical Envelope Encryption model. The key hierarchy includes: 1. Customer Managed Key (CMK): The Root of Trust in the cloud KMS, never accessed in plaintext by Databricks. 2. Key Encryption Key (KEK): A transient key for wrapping data keys. 3. Data Encryption Keys (DEKs): Unique keys for each data segment, stored in an encrypted state. When data access is needed, Lakebase retrieves DEKs by unwrapping keys from the KMS. If a key is revoked, access to the data is denied, and ephemeral compute instances are terminated. In practice, CMK applies to: 1. Persistence Layer (Storage): All data segments are encrypted with keys controlled by the CMK. 2. Ephemeral Layer (Compute): Each compute instance generates a unique ephemeral key, and upon revocation, the instance is terminated, destroying in-memory keys. CMK implementation follows a delegation model, allowing Security Admins to manage keys without accessing data. The process includes key configuration, workspace binding, and lifecycle management. Key rotation is seamless, requiring no data re-encryption. All cryptographic operations involving the CMK are logged by the cloud provider's audit service. Lakebase CMK is available for Enterprise tier customers, allowing organizations to manage their encryption keys effectively.

Databricks Postgres Gets Customer Key Control

Databricks has introduced customer-managed keys (CMK) for its Lakehouse Postgres offering, allowing users to control their data encryption and utilize their own Key Management Service (KMS) from major cloud providers like AWS KMS, Azure Key Vault, or Google Cloud KMS. The Lakehouse Postgres architecture features a hierarchical envelope encryption model with three tiers: the customer-managed root key (CMK), a Key Encryption Key (KEK) used by Databricks' Key Manager Service, and unique Data Encryption Keys (DEKs) for each data segment. If a CMK is revoked, access to the data is denied, and active compute instances are terminated, serving as a failsafe for high-compliance workloads. The implementation allows for granular control over key management and supports seamless key rotation without data re-encryption or downtime. All cryptographic operations are logged within the customer's cloud audit services, available to Databricks Enterprise tier customers.
