Some 45 years ago, we set out with the ambitious goal of providing affordable housing, working to make Brazilian dreams come true. Over the last few years, we have crafted and shaped our story, becoming a brand-leading platform that offers a variety of housing solutions for individuals and families from all walks of life – after all, each person is an individual – and every individual is as important as the next. Our company has joined together the efforts of some 30,000 staff members aiming to build dreams that transform the world – because we believe that purchasing a home is not the end of the line, but the beginning of life-changing transformation and the origin of many dreams for the future. Our company is present in more than 160 cities and 22 states, seeking to bring quality of life, comfort and innovation to the doorstep of thousands of families. And it is our great pleasure to announce that, today, one in every 150 Brazilians has an MRV that they call home. But we don’t stop there. Each development comes with the essential building blocks of a community such as daycare centers, health clinics, paved streets, green spaces, reforestation and much, much more. Because growth and urban development require the balance of social responsibility and sustainability, in addition to meeting the true needs of each community – an essential part of our DNA and an example of our commitment to the people of our communities. Click here to take a look at our company’s day-to-day routine and what we mean when we say: ‘to be MRV’.

Latest Global CVEs (Not Company-Specific)

Description

nimiq/core-rs-albatross is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to version 1.3.0, two peer-facing consensus request handlers assume that the history index is always available and call blockchain.history_store.history_index().unwrap() directly. That assumption is false by construction. HistoryStoreProxy::history_index() explicitly returns None for the valid HistoryStoreProxy::WithoutIndex state. when a full node is syncing or otherwise running without the history index, a remote peer can send RequestTransactionsProof or RequestTransactionReceiptsByAddress and trigger an Option::unwrap() panic on the request path. This issue has been patched in version 1.3.0.

Description

PraisonAI is a multi-agent teams system. Prior to version 1.5.95, FileTools.download_file() in praisonaiagents validates the destination path but performs no validation on the url parameter, passing it directly to httpx.stream() with follow_redirects=True. An attacker who controls the URL can reach any host accessible from the server including cloud metadata services and internal network services. This issue has been patched in version 1.5.95.

Description

PraisonAI is a multi-agent teams system. Prior to version 4.5.97, OAuthManager.validate_token() returns True for any token not found in its internal store, which is empty by default. Any HTTP request to the MCP server with an arbitrary Bearer token is treated as authenticated, granting full access to all registered tools and agent capabilities. This issue has been patched in version 4.5.97.

Description

PraisonAI is a multi-agent teams system. Prior to version 4.5.97, the PraisonAI Gateway server accepts WebSocket connections at /ws and serves agent topology at /info with no authentication.

Description

PraisonAI is a multi-agent teams system. Prior to version 4.5.90, MCPToolIndex.search_tools() compiles a caller-supplied string directly as a Python regular expression with no validation, sanitization, or timeout. A crafted regex causes catastrophic backtracking in the re engine, blocking the Python thread for hundreds of seconds and causing a complete service outage. This issue has been patched in version 4.5.90.
