Analysis by TheMasterCaver in minecraftforum, based on 1.6.4 code:
The game makes 10 attempts at placing a group of up to 10 cactus per chunk of desert, with each group within a 15x15 block volume 7 blocks high and each individual cactus being between 1-3 blocks tall. This means that each group can generate a cactus up to 9 blocks tall (the upper 2 blocks can extend above the volume chosen for the initial block) and 10 can generate a 90 block tall cactus, which would require that 3 attempts at a 3 block tall cactus align per group and each group is 9 blocks above the previous.
Also, attempts from up to 4 adjacent populated regions can also overlap for up to 4 times this height, or up to the world height limit if the generator chooses random locations that high (in 1.6.4 it chooses a y-coordinate between 0-127 with the full range of individual attempts being -3 to 130 but I know that in 1.7 they extended the range to allow for terrain going higher than y=127). This is due to the chunk populator centering features within a 16x16 block area but since the groups are 15x15 blocks they can extend 7 blocks outside of this area; this is also why you may have seen strange things like trees floating over lakes, despite the fact that lakes are placed before trees, same for tall grass and sand.

Analysis by TheMasterCaver in a minecraftforum discussion about the theoretical height limit for naturally generating cacti, based on 1.6.4 code:
The game makes 10 attempts at placing a group of up to 10 cactus per chunk of desert, with each group within a 15x15 block volume 7 blocks high and each individual cactus being between 1-3 blocks tall. This means that each group can generate a cactus up to 9 blocks tall (the upper 2 blocks can extend above the volume chosen for the initial block) and 10 can generate a 90 block tall cactus, which would require that 3 attempts at a 3 block tall cactus align per group and each group is 9 blocks above the previous.
Also, attempts from up to 4 adjacent populated regions can also overlap for up to 4 times this height, or up to the world height limit if the generator chooses random locations that high (in 1.6.4 it chooses a y-coordinate between 0-127 with the full range of individual attempts being -3 to 130 but I know that in 1.7 they extended the range to allow for terrain going higher than y=127). This is due to the chunk populator centering features within a 16x16 block area but since the groups are 15x15 blocks they can extend 7 blocks outside of this area; this is also why you may have seen strange things like trees floating over lakes, despite the fact that lakes are placed before trees, same for tall grass and sand.
The bug
Cactus can generate excessively tall, though it can only grow three blocks high. Fun and harmless generation quirk. Also very old and has been in the game since at least 1.4.7.

According to TheMasterCaver in this minecraftforum discussion (cited in MC-234798), one of the causes of this issue is the chunk populator centering features within a 16x16 block area but since the groups are 15x15 blocks they can extend 7 blocks outside of this area. I know next to nothing about the code, so it would be great to know how plausible this explanation is.

MC-165558.Relates to
MC-895and MC-224235.Can confirm, but i think fixing it would do more harm than good. Also, an extremely tall cactus is very unlikely to happen, and removing this would probably get the seed community upset.
I'm not that sure, the seed community is mostly on older versions of the game. However, as much more game-breaking bugs were marked as "Won't Fix" (I'm looking at you,
MC-111378), this probably will as well.Can confirm 24w06a - Seed: -7877430694532488779 (with all experiments enabled), Coords: -36 74 39
I definitely agree this one does no harm, it's like a fun easter egg. Congratulations player, you found the one in a million chance 6 tall cactus!
