Young Living Essential Oils

youngliving.com

Through the painstaking steps of our proprietary Seed to Seal® production process, we produce the best, most authentic essential oils in the world. We are committed to providing pure, powerful products for every family and lifestyle, all infused with the life-changing benefits of our essential oils. Our community of wellness started small in 1993, when D. Gary Young and Mary Young developed their first organic herb farming and distillation operation. At the time, Gary Young had already discovered the incredible power of essential oils, but because the quality of available oils varied so greatly, he’d been unable to fully harness their potential. Mary’s previous experience in the direct-selling industry enabled the Young's to fulfill their vision and establish a business that would empower its members to share truly pure essential oils with the world. After establishing Young Living in 1994, the Young's developed more farmland in Utah and Idaho and began cultivating lavender, peppermint, melissa, clary sage, and many other herbs. Fueled by a growing demand for top-quality essential oils, Young Living designed and built the largest, most technologically advanced essential oil distillery in North America. In harmony with these efforts, Young Living developed its groundbreaking Seed to Seal® process, which preserves the integrity and potency of essential oils through every step of the production process. Headquartered in Lehi, Utah, with offices in Australia, Europe, Canada, Japan, and Singapore, as well as farms around the world, Young Living stays true to the Young's original vision. With our steadfast commitment to essential oil purity, we’ve inspired millions of people everywhere to experience nature's gifts of wellness, to create abundance as Young Living members, and to discover new opportunities for lifelong transformations.

Global CVEs (Not Company-Specific)

CVE-2026-44453

SUMMARY

h2o is an HTTP server with support for HTTP/1.x, HTTP/2 and HTTP/3. Prior to commit 6b5370d, h2o is vulnerable to a Denial of Service attack when calling alloca under certain conditions. When serving static files, h2o builds the file path on stack, by calling alloca. The maximum size of the memory allocated using alloca can be as huge as ~600KB, which exceeds the default pthread stack size used by musl libc (128KB). If the amount of memory allocated by alloca exceeds the stack size, the h2o server crashes with a segmentation fault, while it tries to touch the guard page. This issue has been fixed by commit 6b5370d.

CVE-2026-44452

SUMMARY

h2o is an HTTP server with support for HTTP/1.x, HTTP/2 and HTTP/3. Prior to commit 8dc37cb, when h2o receives a ClientHello message over TLS or QUIC and it contains a zero-length SNI extension, the h2o server runs over the zero-length hostname while trying to copy the hostname, assuming that it is NULL-terminated. This is a potential denial-of-service attack vector in sense that it might trigger segmentation violation. This issue has been fixed by commit 8dc37cb.

CVE-2026-44436

SUMMARY

Quicly is an IETF QUIC protocol implementation intended primarily for use within the H2O HTTP server. Prior to commit 8b178e6, Quicly is vulnerable to a Denial of Service attack through connection state corruption. In QUIC Invariants, the maximum length of a Connection ID is 255 bytes, while QUIC version 1 further restricts the maximum to 20 bytes. Quicly implements QUIC version 1 and therefore its CID buffers are limited to 20 bytes. However, to be able to respond to unknown versions of QUIC, its packet decoder accepts Connection IDs of up to 255 bytes. As its CID buffers are merely 20 bytes long, Quicly must reject QUIC version 1 packets with Connection IDs longer than that. The command line tool bundled with Quicly has had that check, however the library itself lacked such enforcement. As a consequence, when used by applications that lack their own enforcement, the connection state becoming inconsistent to buffer overrun. Fortunately, the overflow stops within the allocated chunk of memory, but nevertheless, the bug leads to assertion failures. This issue has been fixed by commit 8b178e6.

CVE-2026-44434

SUMMARY

Quicly is an IETF QUIC protocol implementation intended primarily for use within the H2O HTTP server. Prior to commit dccf5d4, Quicly was vulnerable to stateless reset injection through lack of packet entry validation. The QUIC protocol is designed to withstand packet injection attacks, once the handshake is complete. Only packets that carry some secret patterns are considered as stateless resets. Quicly allows the peer to share up to 4 such patterns per connection. However, until now, it failed to determine which of the 4 slots that it uses to retain the secret patterns contains a valid entry. As the slots are zero-initialized, the failure meant that, unless the peer advertised 4 of such patterns, an all-zero pattern was treated as a stateless reset.In effect, this allowed an on-path attacker to reset QUIC connections governed by Quicly. This issue has been fixed by commit dccf5d4.
